assertion "state == CHANNEL_STATE_*" errors

During start up I get the following error after which tor bails out:

Bootstrapped 20%: Asking for networkstatus consensus. Bootstrapped 50%: Loading relay descriptors. channel_closed(): Bug: src/or/channel.c:1315: channel_closed: Assertion chan->state == CHANNEL_STATE_CLOSING || chan->state == CHANNEL_STATE_CLOSED || chan->state == CHANNEL_STATE_ERROR failed; aborting.

One possible reason for this error could be that tor is trying to connect to bridges (I use a lot of them) which are not responsive/non-existent/inactive/off-line.

As soon as removed those from my torrc file and left only the ones which (currently) work, then all is well and I don't get the above error.

Please let me know if you need any more info.
