If you are getting the exact crash then the potential workaround could be
xdg-open ~/.local/share/desktop-couch/couchdb.html in a terminal, it will open your browser then enter the database there and hunt and destroy(remove ;)) entries with the name gwibber_* and then logout and login again and try to start gwibber :)
