Ubuntu 13.04 mounts iPhone disk spaces and after a while unmounts them

iPhone 4, iOS 6.1.3, Ubuntu 13.04

On 12.10 and before, I could mount my iPhone without problems. Ubuntu mounted automagically two “shares”, “iPhone” and “Documents on iPhone”, and you can access your files there. If you setup iTunes on a Windows virtual machine, you can even sync your music!

BUT… on version 13.04, Ubuntu mounts THREE iPhone “shares”, the previous two and another one called “Internal Storage”, which points to the DCIM photo directory. The thing is, after a while (~5min), everything is unmounted except this “Internal Storage”.

For what I have been reading and testing, it seems like systemd is killing usbmuxd because it runs as root. The old SysV init didn’t have a problem with that. If you run usbmuxd manually and as root (sudo) the thing works.

Any one experiencing the same behaviour?
