Code review comment for lp://staging/~dylanmccall/notify-osd/sounds-support

This patch causes notification bubbles not to show up at all (but attached sound-files are played). I'm not sure what's causing the bubble not to appear. I've used these to commands to test this on current natty:

notify-send "Incoming call" "Yo dude, answer the damn phone" -i ubuntu-logo --hint=string:sound-file:/usr/share/sounds/ubuntu/stereo/phone-incoming-call.ogg

notify-send "Line busy" "Please call again later" -i gnome-foot --hint=string:sound-file:/usr/share/sounds/ubuntu/stereo/phone-outgoing-busy.ogg

I see and hear the first bubble, but the second bubble does not get displayed. I only hear the sound file played of the second one.
