-- Information about the crash:
This crash behavior (4-5+ times/day) astarted in the last few days.  When it
happens everything seems to recover and work can contiue after clearing the
crash message.

Another issue, possibly related(?) arose yesterday ~noon - the first time I
have ever seen it --"notify cannot be used, reverting to polling: Too many open
files”?   I increased the limits and that error has not repeated this morning.

Other software open at the time
occular/chromium/dolphin/soffice/kterm/thunderbird

This computer is running a relatively new upgrade to Trixie from Bookworm
Linux rock-3 6.12.57+deb13-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.12.57-1
(2025-11-05) x86_64 GNU/Linux

I suspect this may issue have been caused by an upgrade?

The reporter is unsure if this crash is reproducible.
