O_o. I still find a lot of random crud uploaded as other things on commons.
We reliably detect Ogg as far as I can tell, at least in the sense
that when I've checked in the past all the files on commons that had
the bad mime data in the database were actually not ogg files.
I'll have to check more carefully but if we are, as I believe,
correctly detecting Ogg files then we could turn on limiting on those

I just conducted a test:
[gmaxwell at bessel ~]$ file ./.wine/drive_c/windows/system32/cmd.exe
./.wine/drive_c/windows/system32/cmd.exe: MS-DOS executable PE for MS
Windows (console) Intel 80386
It did reject the exe renamed to both png and jpg but thats it.

I'm not, but I honestly thought this was 'works as designed'.
At least in the ogg case we may already have reliable enough
detection.. if something is lacking there it should be trivial to fix
ogg is easy to detect robustly. I don't know about the other file
