See the bottom of the log: "Attempt to unlock mutex that was not locked"
The problem is that glib 2.42, used in Ubuntu 14.10 became more strict about lock checking, and you're using a version of gvfs from a older version of GNOME which had a locking bug. See this commit https://git.gnome.org/browse/gvfs/commit/?id=2153d300f24d3388d7c4ab75a55451ad5a581b5a
Unfortunately, mixing and matching bits from different GNOME releases can cause problems...
For a solution, you could ask the Ubuntu maintainers to add that patch.
