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

[Jonathan Kamens]

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.

I'm not sure, but this may qualify as `regression-release`, because I actually use xdg-open to open mp3 files, which worked reliably in 17.04 but is failing in 17.10 because of this `gio open` problem.
