Bug ID: 389506
Summary: Kate crashes when invoking some vi commmands with only
one empty file open
Product: kate
Version: 17.04.3
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: kwrite-bugs-n...@kde.org
Reporter: fed...@wp.pl
Target Milestone: ---
Application: kate (17.04.3)
Qt Version: 5.9.1
Frameworks Version: 5.41.0
Operating System: Linux 4.2.0 x86_64
Distribution: Ubuntu 17.10
-- Information about the crash:
Example commands that crash the editor:
:e <random file name, kate will crash even if path is correct>
:enew
Both of them crash kate only when there is one empty file open. If I would edit
that file or open an already created one, both commands will work properly.
Both File->New and File->Open work alright.
The crash can be reproduced every time.
-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
