It was actually the update of libglib2.0-0 to 2.40.0:

   - g_source_remove() will now throw a critical in the case that you
     try to remove a non-existent source.  We expect that there is some
     code in the wild that will fall afoul of this new critical but
     considering that we now reuse source IDs, this code is already
     broken and should probably be fixed.

Now to figure out where Vim is screwing things up.

Indeed.  I tried adding your guicursor modification to my vimrc and it worked
fine.
