When enabling bridges, the log view goes entirely blank

I just enabled bridges (didn't enter any). Going to the log view now shows a black screen. The symbol is still green, so Tor is probably still running. Disabling bridges again doesn't make the log return. Shutting Tor down and then going to the log gives me a log again, starting with "Shutting down...". After starting Tor again, however (with bridges disabled), the log is completely blank again.
