Comment 4 for bug 1393650

Additional Facts:

I have installed Ubuntu Mate 14.10 on 4 computers and then installed Audacious. I find one of the four is NOT affected by this problem.

On one of the 3 affected computers, I have installed Ubuntu MATE 14.04 in dual boot and find that the problem did not show up in 14.04.

Opening folders with the file manager does NOT produce the problem on any machine, so Audacious would not be the default for opening folders. It is only from the panel Mint Main Menu > Places, or the panel Menu Bar Places Menu that the problem manifests itself.

Only the unaffected computer shows a right-click menu option to "Open With Audacious" The three affected machines lack this entry. That is strange.

As a test, I removed "inode/directory" from the MimeType= line on one affected machine and rebooted. The problem still exists.

"inode/directory" is shown as a MimeType in the unaffected computer as well. If this were the cause, I would expect this one to be affected too.
