Bug#1108739: baobab crashes when a MTP device is "mounted"

[Julien Plissonneau Duquène]

Package: baobab
Version: 48.0-2+b1
Severity: important
X-Debbugs-Cc: sre4ever at free.fr

Dear Maintainers,

This application crashes with a SIGSEGV when attempting to start it while a MTP
device is mounted through GVFS. When the device is plugged but not mounted, the
application starts, but crashes when attempting to mount the device by clicking
on it. I did not try to reproduce the issue with a different device.

Below is a crash report of starting baobab with the device already mounted.
