Description James Beddek 2022-10-14 01:06:10 UTC

Application: dolphin (22.08.1)
 (Compiled from sources)
Qt Version: 5.15.5
Frameworks Version: 5.99.0
Operating System: Linux 6.0.0-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.26.0 [KCrashBackend]

-- Information about the crash:
Dragging any file/folder into the folder path location bar, attempting to move the file/folder results in a crash 100% of the time.
This appears to be a regression with KF 5.99. This issue only starting appearing after building dolphin against KF 5.99
KF & Dolphin were compiled with Clang 15.0.2

The crash can be reproduced every time.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Comment 1 James Beddek 2022-10-15 00:12:17 UTC

I can no longer reproduce this with kdesrc-build. It was reproducible for me yesterday, but no longer since I've updated the sources. I've attempted to bisect any changes which may have had an impact on this with no luck (dolphin, plasma-framework, kwidgetsaddons, etc).

Although it's no longer crashing, the terminal is spammed with "QCoreApplication::postEvent: Unexpected null receiver" while attempting to replicate the crash.

This is still reproducible with release tarballs. I'm looking for guidance here now that I cannot reproduce on master - should this bug be closed or updated to reflect the postEvent spam?

New crash information added by DrKonqi

dolphin (22.08.1) using Qt 5.15.6

Dragging any file or folder into the folder path location bar in Dolphin results in a crash every time.
