Status changed to 'Confirmed' because the bug affects multiple users.

[Loïc Minier (lool)]

This is probably fixed with upstream e620b2f "Adjust to latest libimobiledevice API changes", as seen in http://sourceforge.net/p/gtkpod/libgpod/ci/master/tree/.

[Loïc Minier (lool)]

libgpod (0.8.2-7ubuntu3) saucy; urgency=low

  * New patch, 70_adjust-to-latest-libimobiledevice-API-changes, cherry-pick
    e620b2f from upsteam to fix breakage with libimobiledevice 1.1.5.

seems like that's still an issue (looking to errors.ubuntu.com reports)

[Sebastien Bacher (seb128)]

ignore that, the issue is in libimobiledevice

[Loïc Minier (lool)]

I personally had this issue in the past, and it went away with the fix; I can't reproduce the issue by just plugging a device (just checked again with final saucy packages)

I suspect there might be another issue, probably crashing in the same place (init path) with specific iOS / device combinations, or perhaps specific data or Ubuntu apps; would be good to get one of the new crashes retraced to diagnose this.
