Description willanad 2023-07-27 19:44:45 UTC 
SUMMARY
Application: dolphin (21.12.3)

Qt Version: 5.15.2
Frameworks Version: 5.90.0
Operating System: Linux 5.14.21-150400.24.69-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.4"
DrKonqi: 5.24.4 [KCrashBackend]

-- Information about the crash:
- What I was doing when the application crashed:
Usually, as is the case with this specific report, when I'm doing something that requires frequent invoktion of Dolphin such as saving files to disk in Firefox.

- Unusual behavior I noticed:
After my system has been up for a while, I frequently encounter a situation in which Dolphin, regardless of how it's invoked, refuses to open, crashing immediately with the attached (or similar) bug report. This happens regardless of whether I open Dolphin directly from the desktop, the shell, or even through another application that requires an external file selector such as saving files to disk in Firefox. At first I thought it may be related to some filesystem corruption but I've ran various fsck tools before and after the crash and found no issue; plus, I can still traverse the filesystem just fine from the shell. I suspect (from the crash handler's backtrace) it's a bug in how "file icons" are cached.

- System:
Operating System: openSUSE Leap 15.4
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2

Graphics Platform: X11
Processors: 4 × Intel® Core™ i7-6500U CPU @ 2.50GHz
Memory: 11.6 GiB of RAM
Graphics Processor: Mesa DRI Intel® HD Graphics 520

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Bus error

And a following issue: the above report was created with the help of DrKonqi however it repeatedly failed to actually post the report saying only "Error sending the crash report: /https://bugs.kde.org/rest/bug?token=<TOKENID (changes each retry)>./" thus why I'm posting this manually in such an inelegant fashion.
Comment 1 Ben Bonacci 2023-08-04 09:51:26 UTC 
It looks like you're running an old version (21.12.3) of Dolphin. Have you tried updating to the latest version of Dolphin to see if the problem continues?
And for the DrKonqi issue it looks like it has already been reported in bug 464293.
