Pale Moon Crashes with ABORT: X_ShmPutImage

[Shadeclan]

I'm getting this in my terminal from a private page on BlogSpot after PaleMoon crashes hard:

Code: Select all

###!!! ABORT: X_ShmPutImage: BadMatch (invalid parameter attributes); 29 requests ago: file /home/palemoon/PaleMoon/pmsrc/toolkit/xre/nsX11ErrorHandler.cpp, line 145

Segmentation fault

Using PaleMoon Version: 25.6.0 (x64) - just installed it yesterday on a brand new installation of Linux Mint as I am in the process of ditching Kubuntu.
I can send you the output from troubleshooting info if you need it.
I've installed Chrome (webkit), Maxthon (trident) and Opera (not sure what it uses) as well as the default installation of Firefox - I'll try the page out in the various browsers and get back to you with the results.

Moderator note: Split into separate topic since this is a completely different error message.

Sorry to be the bearer of bad news but PaleMoon is the only browser that crashes. However, I do have additional information. There is a video frame embedded in the webpage. The crash doesn't happen until I scroll down far enough that the top edge of the frame should appear - at that point, PaleMoon just disappears and the error I posted appears in the terminal.

Hope that helps.

Can you post a link to the specific page this happens on?

brand new installation of Linux Mint

x86 or x64? KDE edition?

x86 or x64? KDE edition?

64 bit Mint.

Can you post a link to the specific page this happens on?

This particular page is a private blog on BlogSpot and I can't give it out. However, I'll look around and see if I can find a public page that it happens on.

I have noticed that Linux PaleMoon seems to have issues with video display that Windows PaleMoon does not. For example, going to fullscreen on a YouTube page causes a strange shaking effect but doesn't cause PaleMoon to crash but Windows PaleMoon displays it just fine.

I didn't find that error, but I did find a very reproducible and possibly related issue. Here's the scenario:

I have 2 tabs up. One tab is this forum page. The other tab is the YouTube page I previously posted. I click on the YouTube tab - the page displays and the video starts playing like normal. I click on the forum page - the forum page is displayed. Everything seems fine. Then, without actually returning to the YouTube page, I click the close button on the YouTube tab. PaleMoon crashes but this time it leaves no error message in the terminal!

I'll keep searching for a public page that causes the BadMatch error.

64 bit Mint.

Highlight by me.

Your "scenario" works fine here.

[ketmar]

that may be gstreamer-related. you may try to set "media.gstreamer.enabled" to false, this will disable video playback, but may prevent crashing until the root of the issue is found. dunno if "no video, but no crash" is better then "no video, do crash", though. ;-)

x86 or x64? KDE edition?

64 bit Mint.

I thought that KDE was a desktop / user interface and that Linux Mint uses the Cinnamon desktop / interface instead.

Mint comes in three flavors: Cinnamon, MATE, KDE and Xfce.

EDIT: should read four.... instead of three

I can't explain it.

Started PaleMoon in safe mode - still does it.

I'm using Cinnamon flavor!

Hmmmm ... it's already set to false ...

Setting it to true makes no difference.

[ketmar]

then try to set it to "true". ;-)

[Shadeclan]

then try to set it to "true".

Already did. No difference

[SvenG]

Are you using an old profile? Found some issues with similar errors (similar = on Firefox instead of Pale Moon) on Ubuntu (should be close enough to Mint), that were said to be caused by a broken profile.

[ketmar]

>Already did. No difference
too bad that there are only two possible values. i'm out of ideas. ;-)

[Shadeclan]

Ahhh! Found it! It's one of my plug-ins!

List of Plug-ins:

• DivX Web Player
  QuickTime
  Shockwave Flash
  VLC Multimedia
  Windows Media Player

When I disabled all plug-ins and restarted, the problem went away. I'll pin down which is causing the issue.

[SvenG]

Try Flash first.

[Shadeclan]

Ahhh! Found it! It's one of my plug-ins!

It's the Flash plug-in. Leave it to Adobe to screw everything up!

... and now the private BlogSpot page I spoke of before stopped crashing. There you go. Problem found, if not solved.

Probably should put some sort of error trapping for this plug-in to keep it from making PaleMoon do a nosedive.
