Bug ID: 426822
Summary: KDE menu system crashes at "save"
Product: kmenuedit
Version: 5.18.5
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: wwaus...@gmail.com
Target Milestone: ---
Application: kmenuedit (5.18.5)
Qt Version: 5.14.2
Frameworks Version: 5.70.0
Operating System: Linux 5.8.8-200.fc32.x86_64 x86_64
Windowing system: X11
Distribution: Fedora 32 (KDE Plasma)
-- Information about the crash:
- What I was doing when the application crashed:
I was doing *extensive* edits to the menu system. Upgrading fro FC31 to FC32,
to get rid of serious "stuck focus" problem I finally blew my entire .kde
directory away and started fresh. My from menu was complex and is FAR more
useful for me than the stock menu, so I was editing the menu (adding and
deleting entries) and then saving and testing after each group.
I had (IIRC) between 6 and 9 of the menu-editor over roughly 2 hours of work.
EVERY CRASH HAPPENED AS SOON AS I HIT THE <SAVE BUTTON> - no exceptions. FWIW,
no, the saves did not take place, so I lost a good deal of work. (The former
copy of menu under ${HOME}/.kde/share/applnk is still ignored as it has been
for a dozen or so releases, so it doesn't help but serves as a guide when I
have to rebuild the menu system from scratch.
This did not occur evey time I hit save - only occasionally, usually after a
larger number of changes had been made (20 or more). Only once did it crash
after making only one or two changes. It has happened a couple of times
previously, but not with the high frequency of occurrences I had today.
The crash can be reproduced sometimes.
