[sugar] Problem launching activity with sugar-activity using sugar-jhbuild

[julius at younglucks.com]

I installed sugar with sugar-jhbuild, and used sugar-jhbuild run to  
start sugar.  After going to the developer console, I cd'd into the  
sugar-jhbuild directory and tried

sugar-activity web

The web activity did not show up, and gave a log message:

ERROR - dbus.proxies: Introspect error on  
:1.15:/org/laptop/sugar/DataStore: dbus.exceptions.DBusException:

The git log of my sugar version is

commit f182201b3491365e7ebe19284fb92b07ed90ef7a

Any help would be appreciated.
