I have build libimobiledevice5 1.1.7 from Debian experimental. I wasn't able to build usbmuxd 1.1.0 because of dependency problems, however. With only libimobiledevice-1.1.7 I still get the same error, so I guess both libimobiledevice and usbmuxd need an update. On a current Archlinux installation with libimobiledevice-1.1.7 and usbmuxd-1.1.0 things work as expected and I can access the installed applications on my iPhone (currently iOS 8.1.2). Both packages seem to be stuck in experimental, so I don't know if it's possible to backport them right now.
