Bug 503124

As the message at the top of the template says, if something crashed, we need a backtrace of it so we can figure out what's going on. Can you please attach a backtrace of the crash using the coredumpctl command-line program, as detailed in [https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl](https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl)?
Thanks.

coredumpctl --reverse running Inkscape

coredumpctl --reverse
This tells me that some file is missing; not sure if it is useful

gdb inkscape

I also did this trace (reproducing the crash while gdb is running). However, this time Inkscape only froze and did not crash.

(In reply to TraceyC from comment #1)

Thank you. I tried that, but not sure if the output is useful. Please let me know if you need anything else. Thanks!

There's a similar report in bug 501623, and there was a pull request to fix that crash that fixes it in Plasma 6.3.4

Please share this information as asked for in the bug template

Thanks for the additional system information. From the backtrace, there are still missing symbols for Inkscape itself. Can you please install the debug package for Inkscape and send a new backtrace? 

Thanks

I did some reading about the bug that was fixed, and that did look to be a bug in the Plasma clipboard app (klipper)
This backtrace is different.
There's discussion in this Inkscape gitlab issue about them working on their end of the problem:
https://gitlab.com/inkscape/inkscape/-/issues/5528

Sorry, I did what I can but I am unable to get a useful trace. I now see that the coredumpctl --reverse command you suggested gives only a very old dump according to the timestamp, and that it cannot find a current one, so that trace is definitely useless. Reproducing the crash within GDL (my second attached file) should have all the debugging symbols already, but it does not look useful (in Arch, these are installed by gdl on the fly using Debuginfod, and gdl did install them, and I couldn't find any specific package to install).

After you install the debug packages, you can re-run the backtrace on a past entry in coredumpctl 
Alternatively you can do gdb again. It is necessary to have the debug package for Inkscape, however
You might try reaching out to the EndeavourOS folks to find out how to get it installed, or get the necessary symbols

gdb inkscape

I was able to install the debug package. Here the gdb backtrace (trace attached).

This time, I had to copy/paste four times, after which Inkscape froze. After each copy/paste, it seems to try to start a new Inkscape instance (I think so since it is extremely laggy and the splash screen appears).

In addition, the gdl output contained this error (only in the terminal, not in the saved trace):

I didn't call that gimp plugin at all, nor did I create any .xcf file (I just created a new rectangle using the "Rectangle tool" and copy/pasted it within the Inkscape window), so this one is mysterious to me.

Hope this helps!

From the last attachment, it doesn't look like you ran "backtrace" in gdb.

Take a look at "Retrieving a backtrace with GDB" on
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Backtraces

gdb backtrace

Sorry for my lack of expertise. I think I got it now; does the attached backtrace look right? Thanks.

Thanks for all your efforts into testing this.
I'm not seeing anything about Inkscape in that backtrace. To be clear, did you run Inkscape before backtrace?

gdb inkscape
(gdb) run
(cause crash)
(gdb) backtrace

gdb inkscape backtrace full terminal log

Yes, this is exactly what I did. I just tried it again, and this time attached the full terminal content, including all commands that I entered.

Thanks for your persistence and the detailed backtrace. I am not seeing any klipper or KDE related code in it. 

In the Inkscape bug I sent the link for, someone else looks to have encountered the same crash and has the same backtrace:
https://gitlab.com/inkscape/inkscape/-/issues/5528#note_2399268227

This bug appears to be within Inkscape, I recommend following the bug on the Inkscape tracker. I'll close this out, since there's no code the KDE developers can fix. Thanks for your understanding.
