Bug 309845

Application: kdevelop (4.3.1)
KDE Platform Version: 4.9.3 "release 520"
Qt Version: 4.8.3
Operating System: Linux 3.4.11-2.16-desktop x86_64
Distribution: "openSUSE 12.2 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:
Trying to import a project from kde (plasma-mediacenter)

It crashed every time I tried.

https://bugs.kde.org/show_bug.cgi?id=278252
seems to be very similar, but that bug was closed 2011-08-09 08:21:01 UTC . Even so there too is one new crash report including a backtrace on a recent version of KDE Platform and Kdevelop

The crash can be reproduced every time.

-- Backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
