Last night I was trying to make XMMS my default player for ogg files so I right-clicked on an ogg file, clicked open with, typed xmms in the bar, and checked "Remember application..." Everything seemed to be fine, but then I clicked on a folder in Konqueror and it tried to open in XMMS. I deleted XMMS as an application to open folders with by right clicking a folder and clicking properties. Now when I try to open a folder I get an error like this:

"There appears to be a configuration error. You have associated Konqueror with inode/directory, but it can't handle this type of file."

Any help?

that's geting kind of strange there isnt it
easiest thing to do when kde config goes south of the border
delete the ~/.kde folder and restart kde
will get config wiz again and it will give your configs a fresh rewrite

Go into KDE Control Center, Components -> File Associations. Change it back
