As far as I can tell, if a file contains a password (obfuscated) Konqueror
doesn't recognize the file type.  For example, on my system (Slackware
12.2 with KDE 3.5.10) Konqueror fails to recognize both kmailrc and
kopeterc.  If I make a copy of kmailrc and remove the password lines,
then Konqueror recognizes the file as plain text.
