NO filenames in URL (photo/video/files)

he guys i have a problem with my dolphin 7beta install!

in the photo/video/file section the filenames are NOT! displaying in the URL´s

http://www.mydomain.com/photo/gallery/FILENAME

i get

http://www.mydomain.com/photo/gallery/- or http://www.mydomain.com/photo/gallery/-2009-07-21-6

on my second server works it, so i think its a server misconfiguration...

anybody an idea!!

Try to post normal latin titles for permalinks to avoid text disappearing

it dont work !!
