Bug#684985: kdevelop crashes when adding new line
Package: kdevelop
Version: 4.3.1-3+b1
when trying to add a new line in a file, kdevelop violently crashes.
It happens sometimes (twice in a row today) and somewhat quite often.
kdevelop was started with a session and no project.
On Debian testing AMD 64, kernel 3.2+45, up-to date.
Run with XFCE (so no KDE is installed).
This happens with both my computers (1st: AMD FX, nVidia proprietary
drivers, 2nd: AMD Athlon X2, ATI Radeon proprietary drivers).
Note that the crash can still occur even without non GPL modules loaded
to the kernel.
Below is the backtrace:
Application: KDevelop (kdevelop), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
