opimd: a bug (?) and how to list missed calls?

[arne anka]

following  
http://lists.openmoko.org/pipermail/community/2009-September/054567.html:

mdbus -s org.freesmartphone.opimd /org/freesmartphone/PIM/Calls/Query  
org.freesmartphone.PIM.Calls.Query {'Answered':0}
ERROR:dbus.connection:Unable to set arguments ('{Answered:0}',) according  
to signature u'a{sv}': <type 'exceptions.TypeError'>: string indices must  
be integers

but

mdbus -s org.freesmartphone.opimd /org/freesmartphone/PIM/Calls/Query  
org.freesmartphone.PIM.Calls.Query {}
/org/freesmartphone/PIM/Calls/Query: Query ->   
/org/freesmartphone/PIM/Calls/Queries/1
