No. Kmail directory doesn't exist under apps: [root@localhost apps]# ls -all total 24 drwx------ 6 root root 4096 May 3 20:51 . drwx------ 8 root root 4096 Apr 27 21:01 .. drwx------ 2 root root 4096 Apr 27 21:16 kfile drwx------ 3 root root 4096 Apr 27 21:01 kfm drwx------ 2 root root 4096 Apr 27 21:13 konqueror drwx------ 2 root root 4096 May 3 20:51 RecentDocuments When I start Kmail from terminal, here's the output: First time: [rory@localhost rory]$ *** KMail got signal 11 (Crashing) KCrash: Application 'kmail' crashing... Backtrack: unable to create a valid backtrace Second time I ran from root. It crashed, saying there was a conflict with artssound, which it then prompted me to disable when I ran it again. So, I can get it to open via root now, but not from the panel or from terminal when I'm not signed in as root - it crashes with signal 11. Here's the output via root: [root@localhost apps]# kmail DCOPClient::attachInternal. Attach failed Could not open network socket DCOPClient::attachInternal.
