Yes, that's a typo, I'll fix it.

The signal is actually being emitted by the backend, not the frontend.  The 
frontend simply re-emits the signal (signal connected to signal).  So I don't 
quite follow.

If I remove the backend/ifaces part of it, then in the frontend you have to 
connect the signal from the backend to a slot, determine which object in the 
backend sent the signal (which is the exact issue I'm trying to fix), and 
then re-emit the signal with the proper udi.

Or am I missing something...?

Another thing: This issue (having to monkey around with pointers and have 
messy code to figure out what's sending a signal since the udi isn't being 
passed) is not actually localized to StorageAccess, it's in many of the Solid 
modules.  See, for instance, Solid::AcAdapter and Solid::Battery.  I'm 
wondering if perhaps a comprehensive update across the board should be done.
