It does, indeed:

So for whatever reasons, one of the three dbus-ping calls in
tramp-gvfs.el hangs (for the default 25 sec timeout of D-Bus calls).

Could you, please, check the following patch? It restricts every
dbus-ping to 0.1 sec. It will still leave a short delay for you, but
this might be tolerable.

Best regards, Michael.
