Description Pedro Villavicencio 2011-11-25 04:29:56 UTC 
this report has been filed here:

https://bugs.launchpad.net/ubuntu/+source/upower/+bug/870593

there's no specific steps on how to reproduce the crash, most of users are commenting that the crash appears just after login. Btw is this more like a libplist issue? Thanks!.

Comment 1 Bastien Nocera 2013-10-14 07:32:28 UTC 
It's either a bug in libimobiledevice, or our use of it. I cannot reproduce the problem locally, and the last bug dates back from 2012. As nothing changed on the UPower side, it's likely a problem lower down the stack.
