Bug 333680

Application: kdevelop (4.5.2)
KDE Platform Version: 4.11.5
Qt Version: 4.8.5
Operating System: Linux 3.11.10-7-desktop x86_64
Distribution: "openSUSE 13.1 (Bottle) (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed: I tried to set a breakpoint.
Generally I had difficulties to set breakpoints. Either the program stops although the breakpoint is not set, or when set does not stop. Further, when I want to set a breakpoint it is not always successfull.

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