xnconvert doesn`t work

[vasilbelarus]

Hi! I have the XnConvert deb package (see http://xnconvert.com/downloads) installed on my Kubuntu 11.10 system, but when I try to start the program nothing happen at all. When I try to start program from konsole I see message:

Cannot mix incompatible Qt library (version 0x40704) with this library (version 0x40701)
/opt/XnConvert/xnconvert.sh: строка 5:  2804 Аварийный останов         "$dirname"/xnconvert "$@"

The only I now is that this deb package was working in my old Kubuntu 11.04 system and Ubuntu 11.04, Ubuntu 11.10 systems.
I didn`t have such type of problems before, so I need help.
Sorry for my english, it should be better
