I did some research and found this problem affects only file on a Samba share (at least for me). Also, I tried opening such files while in guest mode and everything worked. My guess is, this is related to some left-over settings from previous installations... I removed settings and temp files for totem and samba (those in my home directory), and solved the problem...
