Qt Version: 6.8.2
Frameworks Version: 6.11.0

-- Information about the crash:
kioworker crashes when opening and using Dolphin. Upon first use of Dolphin, a multitude of crashes was reported within seconds. After some time, the reports stopped coming so fast. Now, after a few minutes (and a restart of Dolphin), the crashes are much less frequent and only occur occasionally, it does not seem to interfere with Dolphin, I can use it normally.

The crash can be reproduced sometimes.

Comment 3 TraceyC 2025-03-10 18:57:25 UTC 
This crash was reported against Dolphin, but the backtrace mentioned calligra, and the last part looks identical to the backtrace in bug 490827, which is for a Save dialog.

If Dolphin is still crashing at start up, can you attach the first backtrace that comes up for it? Thanks.
