Bug ID: 470348
Summary: Segfault when manipulating configuration
Classification: Applications
Product: kate
Version: 22.12.3
Platform: Kubuntu
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: ad...@petermello.net
Target Milestone: ---
Application: kate (22.12.3)
Qt Version: 5.15.8
Frameworks Version: 5.106.0
Operating System: Linux 6.2.0-23-generic x86_64
Windowing System: X11
Distribution: Ubuntu 23.04
DrKonqi: 5.27.5 [KCrashBackend]
-- Information about the crash:
Kate seems to be crashing whenever I make adjustments to several settings at
one time, however if I only adjust one or two items and then click OK, it
behaves as expected. This even extends to resizing various panels in the app,
where if (for instance) I use the mouse to drag the divider between the editor
and the Filesystem plugin to alter the width of the plugin bar once, I can
continue editing without incident. However if over the course of a single
instance I resize the plugin bar four or five times, almost invariably it will
segfault the instant that I release the mouse button. I examined the
permissions on every config folder I'm aware of Kate/KWrite having and found
nothing untowards, nor are the drives they reside on experiencing any I/O load
that might impede the recording of such ephemeral config changes. This one has
me stumped.
The crash can be reproduced sometimes.
-- Backtrace:
