That was a problem with the Deferred chaining in the download command (the
summary is that Deferreds don't handle tail recursion), and is fixed in
current CVS. Ticket #106 covered it. You can probably just apply the patch
referenced therein to your 0.7.6 tree if you don't feel like running
unreleased code.

hope that helps,

#106:  http://buildbot.net/trac/ticket/106
