It's also very common: QuickTime MOV and Windows AVI files work exactly the same 
way. Neither has to contain video although they usually do. Even if the Ogg guys 
were publically larted and vowed to reform we'd still have to deal with that.

Short of some plugin API for MIME type detection (which I've wanted since 
forever) a hack could be to have a simple Ogg Handler program that figured out 
what the 'closest' MIME type is and then forwards the open file request to that 
program. If the Ogg file contains video, it'd go to whatever app handles 
video/x-theora, if not then it goes to whatever app handles application/x-ogg.

Ditto for any other container types that cannot be distinguished by file 
extension (are there any others?)
