I just tried on latest vivid krillin and mtp works fine here through nautilus. I can see and send files to my device through the file manager.

did you guys unlock your devices ? MTP is supposed to close the connection if the screen is locked...

For me yes. I get an mtp error in nautilus with the screen on. Oddly though the icon appears in the launcher and if I click on I then get the time out error.

aha, most likely mtp-server isnt running, i'm just re-designing the whole service handling for USB services currently because teh upstart way we use today is a bit unreliable, that should be ready on monday in a silo ...

can you check if mtp-server is in your processlist ?

The partial fix reverting what caused the issue landed yesterday. Silo 19 still has some other improvements, but not related with this bug.
