Application: okular (0.10.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.1
Operating System: Linux 2.6.31.12-desktop-1mnb i686
Distribution: "Mandriva Linux 2010.0"

-- Information about the crash:
I've recently upgraded to KDE SC 4.4.1 mandriva packages from KDE ftp server, and now every time I try to select a printer other than the default in the print dialog in Okular, the application crashes. It's not restricted to Okular however, Kate and Kwrite (and presumably every other KDE application) crash as well.
I haven't been able to try ro reproduce this in KDE 4.4.2 as the packages are still unavailable, but as soon as I upgrade I'll update the info here.
Thanks

The crash can be reproduced every time.
