Hi Fredrik,

Use the latest CVS version. Probably this problem is related with the wrong 
error handling 
in the function reply_handler_function. 

If you are using dbus pin helper, check if the service is 
running(registered) and if the PinAgent 
d-bus configuration file(bluez.conf) is in the system d-bus configuration 
directory(/etc/dbus-1/system.d/) .

Regards,
Claudio
