I am not sure if this is happening only to me or maybe someone else has
the same problem.
if I add a file type association to some app it works OK during the
current session but it is lost after I restart. For example *.torrent
files are not associated with anything at the begining. I then right
click on some torrent file and select Edit File Type and add a new
application which is opened if I double click on torrent file.
I have kdebase-3.1.3-71mdk installed.
