 I have caught the bull by the horns!

 Backtrace stopped: previous frame inner to this frame (corrupt stack?)

 This is a gdb output on ffado-dbus-server crash. From here, it is pretty
 clear whats happening: Former name of the device was
 <something>ScarryBarry, which can be seen from the leftovers in the call.
 I have set the nickname to SaffirePro40. Now ffado doesnt seem to be able
 to handle this, as the nickname clearly contains lots of non-utf stuff! :)

Strange, since getnickname (at least for Focusrite) returns no more than 16 characters; and ffado-dbus-server effectively returns a 16 characters nickname (your previous report). Which way did you use to change the nickname at first ?
