Freeze when using MTP to copy files

I can connect with my Android device, browse and retreive files. When I copy a file to the device the copy progress bar appears but stops at 12 bytes. Thunar becomes unresponsive and afer a few minues a "libmtp error" message is displayed.

After that thunar is no longer usable. Even when starting a new instance it immediatley freezes. I checked with strace and it always freezes on a poll syscall. The only way to recover is a reboot.

This bug is 100% reproducable.
