[Bug 59703] Import freezes/rhythmbox doesn't exit properly if a wmv file is in the watched directory

[VF]

Public bug reported:

I have a wmv file in a directory I tell rhythmbox to watch. The scanning
of file either completes partially or doesn't start. When I go
Music->Exit, rhythmbox is still running in the background and has to be
killed manually. The terminal output is not helpful, although it does
hang when I quit it and I have to ctrl-c manually. When I remove the wmv
file from the watched directory, rhythmbox finishes scanning and quits
normally.

The file's video codec is wmv9 and audio codec is wma8. I'm running
amd64 so I don't have pitfdll and w32codecs installed so I'm not sure if
that will affect this.

** Affects: rhythmbox (Ubuntu)
     Importance: Untriaged
         Status: Unconfirmed
