I had a similar problem. The theme it was looking for wasn't empty but contained weird characters.
To resolve it, you must edit the following gconf key (with gconf-editor) : apps -> teg -> theme , and put m2 there. I guess the breakage was due to a previous (old) upgrade. I think this bug can be closed now. -- Heretik <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
