When I connect the device first time (protocol MTP), amarok properly identified it and I uploaded music to the device with a covers. When i connect the device second time, amarok brought a list of tracks, and the device reboot.  Amarok creates on the device files *.alb. When I delete these files, amarok mounts device fine. Other programs, such as gnomad, always correctly connect the device.
Opensuse 11.1
Amarok 1.4.10
KDE 3.5.10
Libmtp 0.3.6

Sorry for my english

Please submit a bug report at http://bugs.kde.org, if you do this the developers responsible for media devices will become aware of this issue and help you resolve it.
