For me, this bug (if it's one bug we're talking about) was caused, or exposed, by a recent dist-upgrade to testing. I have a Motorola Xoom that I mount on my Debian wheezy box with:
mtpfs -o allow_other /media/android (run as root). This has worked with no problems since I got the Xoom about a month ago. In particular it was working on Friday evening January 31st. But then: Start-Date: 2013-02-01 00:01:06 Commandline: apt-get -t testing dist-upgrade This upgrade included: Upgrade: mtpfs:i386 (0.9-3+b1, 1.1-4), libmono-system-xml4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), gnome-shell:i386 (3.4.2-5, 3.4.2-6), libmono-sharpzip4.84-cil:i386 (2.10.8.1-6, 2.10.8.1-7), gnome-control-center:i386 (3.4.2+git20121016.29d7c0-1, 3.4.3.1-2), libmono-cairo4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-system-configuration4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-i18n-west4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-posix4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-security4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), mono-gac:i386 (2.10.8.1-6, 2.10.8.1-7), unattended-upgrades:i386 (0.79.3, 0.79.4), libmono-system-drawing4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-system-security4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-corlib4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), mono-runtime:i386 (2.10.8.1-6, 2.10.8.1-7), gnome-control-center-data:i386 (3.4.2+git20121016.29d7c0-1,3.4.3.1-2), libmono-system4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), libmono-system-core4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7), mono-4.0-gac:i386 (2.10.8.1-6, 2.10.8.1-7), gnome-shell-common:i386 (3.4.2-5, 3.4.2-6), libmono-i18n4.0-cil:i386 (2.10.8.1-6, 2.10.8.1-7) End-Date: 2013-02-01 00:02:09 As soon as the upgrade completed, I was unable to mount the tablet or communicate with it at all. % mtpfs -o allow_other /media/android Listing raw device(s) Device 0 (VID=22b8 and PID=70a8) is a Motorola Xoom (ID 1).

And presumably the problem was caused by whatever is different between version 0.9-3+b1 and version 1.1-4. Looking at the changelog, the only likely possibilities seemed to be a dependency on fuse rather than on fuse-utils, or else the move to a new upstream version. I tried purging fuse-utils but that made no difference. I tried to downgrade to mtpfs 0.9-3 0 in stable, but apt wanted to remove grub in doing that, so .... Installing libmtp9 from the experimental repository made no difference. I hope this is helpful.
