Bug 308595

Application: kate (3.9.80)
KDE Platform Version: 4.9.80 (Compiled from sources)
Qt Version: 4.8.3
Operating System: Linux 3.4.13-2-desktop i686
Distribution: "openSUSE 12.2 (i586)"

-- Information about the crash:
- What I was doing when the application crashed:

Kate crashes when using "Close All" multiple times (even when no documents are loaded). Probably introduced with the activities feature.

The crash can be reproduced some of the time.

-- Backtrace:
Application: Kate (kdeinit4), signal: Segmentation fault
Using host libthread_db library "/lib/libthread_db.so.1".
