Description Gert Kulyk 2012-07-25 19:57:20 UTC 
Since I've started testing gnome 3.5.x, I'm no longer able to use apps using libbrasero-media for drive detection (sound-juicer, rhythmbox, goobox).
With the gdbus-port of gvfs (done in 1.13.1 cycle), obviously something changed so that libbrasero-media is reporting to find 0 drives and 0 volumes, breaking the above mentioned apps.

This is e.g. the brasero-media (brasero master) debug output when trying to use sound-juicer with an 18 Track audio cd:

Honestly if they change something on gvfs i would appreciate to have some information on the API change or a patch.
Thanks for reporting the bug.

There was no intentional change nor API change, this was a fallout from port to GDBus (i.e. rewriting non-trivial amount of code).

Sadly the root issue is that there are no guarantees GVolumeMonitor should contain all information right after its creation (it's not even mentioned in the docs), the state is undefined. Given the ability to extend GIO volume monitoring functionality there might be backends requiring some time to gather all information or even doing async ops (which requires mainloop to be running).

Anyway, please report any inconsistencies to gvfs, applications like Brasero depend heavily on the information we present.
