Segfault when copying images while using clipboard manager

Post by tijara » 2020-07-23, 04:02

I'm using CopyQ as a clipboard manager on Linux Mint 20 (same happened in 19).
PM from the Ubuntu PPA crashes consistently upon copying images via right-click context menu while said program is managing the clipboard. I apologize if this is a CopyQ issue, but since PM is the only application that crashes, I'm using it as a starting point.
The crashes happen in safe mode as well. This error is displayed in the terminal:

Code: Select all

I don't get the crashes on Debian Buster-based MX, but I'm using CopyQ 3.12.0. I see that Ubuntu 20.04 has 3.10.0 in its repo, so I assume that's what you're using.

BTW, my OBS repo is not a Launchpad "Ubuntu PPA". as it can build packages for many different distros, though I only know how to use it for the Debian derived ones. People might think one could add it with "apt-add-repository" like a true PPA.

I'm almost positive this is a Qt bug: https://bugreports.qt.io/plugins/servle ... TBUG-56595

I've run into the same issue on occasion when attempting to paste an image from Pale Moon into another Qt-based program, which sometimes causes Pale Moon to crash.
Linux Mint 19.3 Cinnamon (64-bit), Debian Bullseye (64-bit), Windows 7 (64-bit)

Sorry for not mentioning that, I'm also using CopyQ 3.12 from its own PPA.
Pale Moon is 28.11 but this happened with previous versions as well.

That's probably it.
