relocation error & apt-problem

Får dessa felmeddelanden när jag försöker starta vissa program, ex:

totem
totem: relocation error: /usr/lib/libtotem-plparser.so.0: undefined symbol: gnome_vfs_drive_unref

gnome-panel
gnome-panel: relocation error: /usr/lib/libgnome-2.so.0: undefined symbol: gnome_vfs_init

Sedan har jag ett annat problem som inte nödvändigtvis har med det första att göra; apt har bestämt sig för att trilskas. Kan inte installera några paket då följande felmeddelande dyker upp:

apt-get -f install ger följande:

ldconfig: /usr/lib/libfribidi.so.0.0.0 is not an ELF file - it has the wrong magic bytes at the start.
