[Bug 1729012] [NEW] "gio open /tmp/whatever.mp3" only opens the file (with totem) every other time it is called

[Jonathan Kamens]

Public bug reported:

I run "gio open /tmp/whatever.mp3". It silently does nothing, i.e., the
mp3 does not play, and yet exits with status 0. I run exactly the same
command again. It opens totem to play the mp3. This seems to be
repeatable: when I run the command repeatedly, it alternatives between
doing nothing and playing the mp3.

I've attached two files showing the output of strace when the command
succeeds and fails. I can't figure out what the heck is going on.
