Bug ID: 381075
Summary: Cannot search for Calibre in Discover
Product: Discover
Version: 5.10.1
Platform: Neon Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: discover
Assignee: aleix...@kde.org
Reporter: avraham.ish.sha...@gmail.com
Target Milestone: ---
Application: plasma-discover (5.10.1)
Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.8.0-54-generic x86_64
Distribution: KDE neon User Edition 5.10
-- Information about the crash:
- What I was doing when the application crashed:
searching "calibre". every time I search for calibre, Discover crashes. Other
searches perform as expected.
The crash can be reproduced every time.
-- Backtrace:
