update-apt-xapian-index crashed with ValueError in index(): invalid null reference in method 'Document_add_value', argument 3 of type 'std::string const &'

[Xavier Fung]

This comes up again - it seems to related to be related to a software update which may affect Gnome Shell. The last update contains gwibber and a replacement of indicator-me. When the update was done, hovering on activities in Gnome Shell would have thumbnails of other workspace showing in the current one, and the thumbnails are somehow distorted. One has to use Alt-F2 and key in r to restart Gnome Shell to return to normal. I am using the ricotz ppa for Gnome Shell.
