@sikmir how did you get a full backtrace without missing symbols? Our project has similar errors (mattanger/ckb-next#47) and I would like to have a full backtrace. Do you just leave the app running from console?

In our case the segfault occurs for me when the screen dims out and screen lock turns on (so, just default power management settings). I never used any kind of sleep or hibernation.

I'm on Arch.

@light2yellow I'm on Arch too. It doesn't matter how to run the app (from console or not), if you have core dump enabled in you system (ulimit -c unlimited). So, what I do:

$ lz4 -d /var/lib/systemd/coredump/core.goldendict.*.lz4 core.goldendict
$ gdb /usr/bin/goldendict core.goldendict -ex 'bt full' -ex quit

That's it.

So, the default Arch qt-base provides debug symbols? Because what I had above was on Ubuntu and it was a mess of ??. Stacktrace top:

Sorry, this is offtop, but since nobody responded for more than a month here... I don't know whom and where to ask.

Yes, it looks like qt-base provides debug symbols (see 'with debug_info' bellow).

$ pacman -Qo /usr/lib/libQt5Gui.so.5.8.0

Hi, this crash happens on resume from suspend in my Arch install. I've got three files when debugging (a chunk below). The full files are attached.
