Hello

Packages:

    openSUSE openSUSE or 1-Click Install (openSUSE 13.2)
    Fedora Fedora (Packages in the official repositories)
    Debian Debian
    Ubuntu Ubuntu (Packages in the official repositories)

My question
Do you known the name of these packages?

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

I think updating to the latest libimobiledevice (v 1.2) might fix this problem. That version is supposed to add iOS 8 support.
