I'm having a look at this part, and it appears that the module is unloaded
from the IO thread. It is not possible to simply call pa_card_set_profile()
from this context. A workaround is to listen to "state" property changes
and change card profile to "Off" in the DBUS handler if state goes to
"Disconnected". This seems to work, but I'm wondering if there is
another solution.
Do you have any suggestions?

Frédéric
