Bug ID: 364437
Summary: kdevelop crash when logging out too quickly.
Product: kdevelop
Version: unspecified
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kdevelop-bugs-n...@kde.org
Reporter: aschm...@graphtek.com
Application: kdevelop (4.90.92)
Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.5-300.fc24.x86_64 x86_64
Distribution: "Fedora release 24 (Twenty Four)"
-- Information about the crash:
I closed kdevelop with about 8 tabs open, and then immediately went to log out.
I've done this times without number, but this time, it threw an error. It's not
easy to reproduce.
The crash does not seem to be reproducible.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
