Bug#623761: guayadeque: Guayadeque crashes - DBus error

[Autumn Lansing]

I can confirm that this also happens in the upstream svn version of
Guayadeque as well.  I had the same issue today using both an older svn
version and the most up-to-date svn version as well as in the official
Debian package.  Guayadeque was working fine previously.  This problem
seems to have been introduced by a change in another Debian package and
is perhaps not an actual bug in Guayadeque itself.
