Banshee crashes when mounting Motorola Xoom

[Timo Ohr]

Starting with 11.10, Banshee (2.2.0-1ubuntu2) consistently gets a SIGSEGV when I try to mount my Motorola Xoom. Probably due to it not having a media-player-info file. Heres the log:

It doesn't seem to get mounted as a regular drive, though. Nautilus accesses it using the following location: "gphoto2://[usb:002,013]/". There is no mount point in "/media". Other devices, like the Galaxy S2, get mounted as regular usb hard drives and seem to work fine with Banshee.

It does work for the most part in Nautilus though, even though I can't seem to access or copy certain files. I don't really care whether Banshee can access the device, as long as it doesn't crash as soon as I connect it.

Here is the log after adding a valid .is_audio_player file:
