WebDAV double listing

When linking to an image (using a field of type File) some files (and 
directories) now appear twice in the update container window.

When selecting a file/image that is listed twice, both of them become 
bold (i.e. appear as selected).

When the directory is browsed through the webdav, the files are not 
double listed.

I have had a quick look through the slide database tables and they 
appear only once.

Any pointers where to start looking?
