crash minidump

Steps:
0. Use the tabbed UI with View > User Interface
1. Close LO completely
2. Open Writer
3. Very quickly click the right-hand-side hamburger/cog menu
4. Wait for the menu to open and the UI to finish loading
5. Click elsewhere to close the menu, e.g. on document canvas

Result: crash

I could only reproduce with the gtk3 VCL plugin. I couldn't reproduce in Draw or Calc.

Repro on Ubuntu 22.04 + GNOME 42.9 and:

Jim, can you please have a look?

On pc Debian x86-64 with master sources updated today, I fail to reproduce, I supposed I missed something.
Would it be possible to have a screencast?

Also I don't understand why you put "critical" whereas:
- you put low importance
- it's tabbed UI (not the mainstream interface)
- since you indicated in 3) "Very quickly click", I suppose it's not easy to reproduce.
- gtk3 only (so Windows, macOS not concerned, idem for those using gen or kf5 rendering)

Will try.

I get that it feels contradictory. Critical severity because it's a crash, as per [1], but low priority because of the reasons you listed. Always tricky to pick one, happy for others to tweak if they see fit.

Thank you Stéphane for the screencast, I could reproduce this on pc Debian x86-64 with master sources updated today.

BTW, I also noticed this on console:

Comment 6 Jim Raykowski 2024-05-04 17:27:20 UTC 
I haven't been able to repro the crash using recent master debug and non-debug builds.

Ubuntu 22.04.4 LTS
libgtk-3-0:amd64 3.24.33-1ubuntu2

I do see in the console:

I think code from this patch was removed by:

But I can still crash it in the same way at 68c96a54fef93b9f735aeb6c9ae07171e934132a (build [d1a552fed0df01b81fa22d4bda5fbf2403a1421b] in linux-64-7.0 bibisect repo), 68c96a54~1, and a current daily build...
