Okay, that command tells me Type: GProxyDrive (GProxyVolumeMonitorGdu).

For the drives that work, it jumps thru glib's g_drive_get_volumes() 
back to gvfs' get_volumes() in file ggduvolumemonitor.c.

However, for the drives that don't work, it doesn't do that. I haven't 
found out yet what kind of GDriveIface G_DRIVE_GET_IFACE (drive) fetches 
in g_drive_get_volumes(). One thing is certain: iface->has_volumes() is 
0, there!

(Any hints how to further debug this? I tried to find out what code is 
called with iface->get_volumes() using gdb, but wasn't successful. I do 
have to admit I'm new to glib and, errhm, to object-orientation in C in 
general.)

  -richy.
