gconf 2.28.0: depending on dbus-x11 fixes ORBit issues and bump PR

If we don't depend on dbus-x11 starting /etc/x11/xserver-nodm output messages like:
  GConf Error: Failed to contact configuration server; some possible causes are that you
  need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system
  crash.
I think gconf is the right package to depend on dbus-x11 because:
  work/.../GConf-2.28.0/po $ grep "GConf Error:" en_GB.po
  msgid "GConf Error: %s\n"
  msgstr "GConf Error: %s\n"
And :
  grep "Failed to contact configuration server" en_GB.po
  "Failed to contact configuration server; some possible causes are that you "
  "Failed to contact configuration server; some possible causes are that you "
And:
<khem> GNUtoo: I have seen this error with firefox on my desktop
<GNUtoo> yes but I wonder where to add the dep,then not in matchbox-something
<GNUtoo> maybe in gconf
<khem> yeah gconf seems best
