Power applet crashes when iPhone plugged in

[CrystalMageX]

What you expected to happen? The power applet not to crash.
What actually happened? The power applet crashed.
If possible, a minimal series of steps necessary to make it happen, where step 1 is "start the program"

1. Make sure the "Power Manager Plugin" is in the panel.
2. Plug in the iPhone.
3. Wait / Click on the power applet.

This seems to occur randomly, sometimes it crashes immediately after re-executing in the "crashed within 60 seconds" dialog, sometimes it is crashes a few seconds after the iPhone is plugged in, sometimes it is appears stable for a while.
