 Replying to [comment:10 arma]:
 > >Make the bridge with capacity != 0 nonworking: The Tor client breaks,
 because it wants to use the bridge with capacity. It doesn't try the other
 bridge, because it has a weight of 0."

 > Is that really happening? If it is, it's a bug that we should fix. The
 fix is not to start weighting bridges differently. It's to make Tor notice
 when a bridge has broken.

 I just tried to reproduce (ran bridge on moria:9009 with bandwidth 50KB,
 and bridge2 on moria:9010 with bandwidth hard-coded in the descriptor to
 0). Run with tor client with
 {{{
 UseBridges 1
 bridge 128.31.0.34:9009
 bridge 128.31.0.34:9010
 }}}
 Started it, it used 9009 exclusively (since it has bandwidth). Then I
 killed the first bridge, and it smoothly moved over to making circuits
 with bridge2.

 Sebastian, can you still reproduce this bug?
