thanks a lot, the problem was solved - there is necessary to reinstall 
the package shared-mime-info

rpm -ivh --force shared-mime-info-0.19-5.el5.i386.rpm

and after that it works fine again. It was a problem of Fedora Core 6 - 
the time from the time it was broken after an update and it seems that 
CentOS has the same problem as well. Before I sent my mail, I checked 
the integrity of the package shared-mime-info and time stamps of its 
files, and everything was OK. I still don't know the real reason, 
however it works.

Best Regards
