problems with cups

[Michal]

Hello,

Every time I choose "print" or "print preview" option in my X 
applications (for example firefox, okular, thunderbird) then my system 
freezes. WCPU of given program goes up to 100% very quickly and I cannot 
kill it or even shut down the machine cleanly.

I got that problem both on 8.0 (amd64) and 7.2 (i386). It's all good 
without cups-client. Problem occurs only after it is installed on my 
systems.

Any ideas, please?
Michal
