[Buildbot-devel] FileDownload step never finishes

I have a FileDownload step that never finishes. I have some other
FileDownload steps on my builders, which work fine, only just one that
never ends.

This was happening in 0.7.4, and still happens in 0.7.6 after I upgraded
everything (Twisted 2.4.4, Linux master and slave).

I have tried to debug this for a while, and here's what I found:

The download on the slave seems to work fine, and the last _readBlock
reads 0 bytes:
2007/11/16 15:02 CST [Broker,client]
SlaveFileDownloadCommand._readBlock(): readlen=0
2007/11/16 15:02 CST [Broker,client] send a remote close

I see the close being called on the master, but nothing further happens.
For the other FileDownload steps, I normally see the 'step complete'
message in the log right after remote_close has been called, and the
builder then continues.

Any ideas what's going wrong? What in the code I should look at from there?
