Bug ID: 494541
Summary: Kate crashes in
KateTextHintProvider::textHintRequested() when
quick-tiling window
Classification: Applications
Product: kate
Version: Git
Platform: Other
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: sessions
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Everything KDE from today's git master
STEPS TO REPRODUCE
1. Have two sessions
2. Launch Kate
3. Switch sessions (I do it from a button I put on the toolbar)
[This often causes the window to resize because window sizes are saved on a
per-session basis]
4. If the window got resized to be maximized, immediately quick-tile the window
to the left or right side of the screen with Meta+Left Arrow or Meta+Right
Arrow
OBSERVED RESULT
Kate crashes with the following backtrace 100% of the time:
Core was generated by `/home/nate/kde/usr/bin/kate -b'.
