Bug ID: 460020
Summary: kmail crashes when running over xpra while using
dosbox
Classification: Applications
Product: kmail2
Version: unspecified
Platform: Compiled Sources
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdepim-b...@kde.org
Reporter: ka...@seznam.cz
Target Milestone: ---
Application: kmail (5.20.3 (22.04.3))
(Compiled from sources)
Qt Version: 5.15.5
Frameworks Version: 5.96.0
Operating System: Linux 5.15.69-gentoo x86_64
Windowing System: X11
Distribution: "Gentoo Linux"
DrKonqi: 5.25.5 [KCrashBackend]
-- Information about the crash:
I'm running kmail from another machine via xpra/ssh session.
When I start dosbox in fullscreen, sometimes starting a game switches
resolution multiple times, making dosbox going forth and back from fullscreen
to windowed.
Kmail crashes reliably during these wild screen changes. (Simple screen change
during dosbox startup/close isn't enough to trigger the crash.)
The crash can be reproduced sometimes.
-- Backtrace:
Application: KMail (kmail), signal: Aborted
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
