Bug 300521

Application: kcharselect (v1.11)
KDE Platform Version: 4.8.3 (4.8.3) (Compiled from sources)
Qt Version: 4.8.2
Operating System: Linux 3.4.0-rc6-1-desktop i686
Distribution: "openSUSE 12.2 Milestone 4 (i586)"

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

While trying to reproduce crash report from bug 300502, I got this backtrace. When kcharselect is started without an installed "kcharselect-data" file, then trying to search causes this crash.

The crash can be reproduced every time.

-- Backtrace:
Application: KCharSelect (kcharselect), signal: Segmentation fault
