Hello I should point out a related thing that can also be considered
to be a bug in the R5 implementation.  I discovered during coding
FileType that GetSupportingApps returns an error in this case:

1. you have an app that handles "image"
2. you have some file type like "image/weird"
3. no application ever handled "image/weird"

The very weird part is the "ever" of #3, because if you defined an
app to handle that type at one point and then removed it, then
it returns B_OK. (and returns apps handling "image")
