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

In the system-config-printer-kde tool, I tried the menu on Add Printer and a
"Printer Class".

I can reproduce this, if needed I can try to create a valgrind trace.


Attached is a 3-star backtrace

The crash can be reproduced every time.
