emulator: mtp-server fails to start, respawns immediately -> high CPU load / log spam

I think the bug title and the logs attached by ubuntu-bug explain my issue:

mtp-server fails to start on emulator image 105 (devel-proposed i386) because there is no /dev/mtp_usb device. After the process quits, it is instantly respawned, just to fail again. The emulator is now 0% idle because it uses all the processing ressources to spawn apport, mtp-server and (juding by PID delta between mtp-server processes) 8 other processes over and over again.
