Summary: Kdevelop crash n edit python source after collapse
Ctrl + Shift + -
Product: kdevelop
Version: 4.2.0
Platform: Ubuntu Packages
OS/Version: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: general
AssignedTo: kdevelop-bugs@kdevelop.org
ReportedBy: tomas.h@wp.pl
Application: kdevelop (4.2.0)
KDE Platform Version: 4.6.1 (4.6.1)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-28-generic x86_64
Distribution: Ubuntu 10.10
-- Information about the crash:
- What I was doing when the application crashed:
1) Open python file with lots of small python class pylons_app/model/form.py
2) Collapse to Top level (Ctrl + Shift + -)
3) scroll down to some class
4) expand one specified class and remove two or three or more comments (remove
# from #some code)
5) crash (not immediately, sometimes take 0-4 seconds when I do nothing)
Note: Kate has the same effect -> crash, the same file
kde4.6 Kubuntu 10.10 64bit
The crash can be reproduced every time.
-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
