28.4.1 crashes in Dpup Stretch-7.5

[doffen]

I run a Puppylinux Dpup Stretch-7.5, based on Debian Stretch 32-bit binaries, with kernel 4.9.149-i686-pae. My laptop is a Dell Latitude E6230, which is known for swallowing most Linux software. It is set up with Lick, for multi-boot choices between Windows 10 and several Puppys.

The Dpup came with PM 28.2.2 pre-installed, but was upgraded by me to 28.4.1 32-bit, by using the upgrade function in the Help menu choice.
The 64-bit version of 28.4.1 was installed by me, to Windows 10.

My problem is a login page on a site from a telecom company, telia, here in Norway. I can open their homepage https://telia.no, but when I click the login button, which normally would take me to a login window on https://telia.no/min-side, palemoon crashes.
The Windows version also crashes, but with a warning, at the same site.

I have tried running an original Dpup install with the default PM 28.2.2, and everything works as intended.
An old PC with a Lucid Puppy and PM 27.9.4, also log in at the telia site without problems.

Were there changes made between the 28.2.2 and 28.4.1 versions, that could lead to my problem?

Confirmed cross-platform UXP issue. Looks to be a nullptr (cause VS directly said it was a nullptr) in svg mask handling somewhere..

Primary SVG code was last touched by kn-yami in https://github.com/MoonchildProductions/UXP/commit/b241a84d884293e1ce49a79c75e362c02c0899f9 but may or may not be directly related to that exact commit but something over all as part of Issue #908 (UXP) for which kn-yami was heading up.

[doffen]

Thank you. And translated into a normal, human language, what does that mean?
And what to do about it?

[New Tobin Paradigm]

It's a crash and needs to be fixed. There isn't anything you can do about it. Me neither because I am shit with cpp.

I was just documenting it as best I can because I was able to reproduce it with my Navigator that I have debugging symbols for even though I am not very good with that either.

[yami_]

This may be our version of bug #1360343. However Tobin's call stack says it crashed on line 214 which is an if condition.

[Moonchild]

Aside from what i suggested on IRC this might in fact also be a crash cause. it crashes on the "if" because "this" is null upon entering that function, so whatever the first expression is that uses any reference to it will likely crash. Adding both fixes should cover the most ground

[yami_]

FYI this issue is tracked as Issue #1034 (uxp) on the UXP bug tracker.

[doffen]

Thank you, Tobin, yami_ and Moonchild. <I'm smiling>
(jeez, what happened to an ordinary 'smiley'?)

[doffen]

I just downloaded v.28.5.0, and so far, everything works as it should, the problem is solved. Thank you!
