Bug 285286

Application: kcmshell4 ()
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to print a testpage of PDF Printer.
Crashed each time.
When I pressed "Print testpage", information in printer applet appeared for a moment, then disappeared.
No other signs of work (no asking for file name, etc.).

PDF printer installed additionaly from cups-pdf (2.5.1-7).
No other printers tested - I got any one.

The crash can be reproduced every time.

-- Backtrace:
