Description V De Groote 2012-04-07 12:35:21 UTC

Application: kdevelop (4.0.2 (using KDevPlatform 1.0.2))
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-32-generic i686
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
Everytime I start Kdevelop, it crashes after a few seconds.  The user interface seems to be right, and in the lower right corner, there is a progress bar which shows "0 %".  The source files are valid (the project compiles successfully with its makefile).

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop.bin), signal: Segmentation fault

Comment 2 Milian Wolff 2012-04-07 13:15:15 UTC

update to kdevelop 4.3 and this will be fixed - 4.0 is very outdated

Comment 3 V De Groote 2012-04-07 13:24:23 UTC

This version seems to be the latest available on ubuntu (synaptic
package manager shows the latest version as "4:4.0.2-0ubuntu2").
Does this means I have to compile KDevelop myself from sources ?
Thanks for your reply

Comment 4 Milian Wolff 2012-04-08 17:11:12 UTC

This is a question you should direct at your distribution's support channel. The answer is most probably: update to a newer Ubuntu or compile from sources. But again: Off topic here, ask your distribution people.
