Forwarded from Debian BTS (http://bugs.debian.org/745783), the last working version was 1.1.6-20-g1b9f164-2:
Package: libmtp9
Version: 1.1.6-51-g1a2669c~ds0-1
Severity: normal
When I try to use any program using libmtp9 (jmtpfs, mtpfs, gvfs with
the mtp backend), I get a segfault:
vauxhall ok % gdb --args mtpfs ~/mnt/test

At least gvfs used to work with this very same device, so this appears
