Description dmakovey 2024-11-29 21:16:01 UTC 
I've recently upgraded from F40 to F41 and the first thing that I've noticed that whenever I unplug my Dell Precision 5690 from Thunderbolt hub I get multiple applications crashing immediately after. I have sent in the reports, but I believe problem lies not the the crashed apps but someplace else and deserves a separate report. 

Reproducible: Always

Steps to Reproduce:
1. Login to Plasma Workspace
2. Plug-in Thunderbolt cable (charging+periferials). This step can be #1 as well 
3. Use second screen through Thunderbolt connection
4. Work a bit plugged in
5. Unplug Thunderbolt cable
Actual Results:  
multiple application crashes

Expected Results:  
No crashes

Snippet from system log around the time of crash

I've attempted to capture most of /var/log/messages from around the time of crash

log inspection shows a lot of SERV terminations (Signal 11) for all applications:
