Bug#942832: usbmuxd freezes when connecting iPhone6 while locked

[Diego Escalante Urrelo]

Forgot to add that when logging in into my GNOME session, if my iPhone
is connected, I experience a long freeze too. I thought it was mtp or
gvfs-gphoto2, but it's probably usbmuxd there too.

Hope you can give me some ideas to fix this, thanks!
