Hi Can you try install libprison-dbg and reproduce and provide the stacktrace? /Sune - prison hacker Created attachment 66237 [details]
New crash information added by DrKonqi
klipper (v0.9.7) on KDE Platform 4.7.2 (4.7.2) using Qt 4.7.4
- What I was doing when the application crashed:
Klipper had three entries, one of which was seemingly empty (perhaps whitespace or some weird problem with klipper?)
The empty entry was the active item.
I opened the menu and clicked 'create barcode'. At this point, klipper crashed.
I installed libprison-dbg as was requested so hopefully my backtrace will be useful.

In my case, the empty entry was a carriage return, because I had selected a line by accident. I can reproduce the crash every time. Just copy one empty line which only contains spaces, then ask klipper to create barcode for it. Both klipper and libprison are built from master code.
