You typo'd the errback method name above. This doesn't cause the problem
you're having, though.

There appears to be a bug in FX_EOF handling in filetransfer.py which
results in the problem you see. It's not completely clear to me why
cftp.py doesn't encounter the same issue. I filed #3009 in the Twisted
issue tracker for this problem. I twiddled the source a bit and seem to
have fixed it, so I think the issue should be easily resolvable. If you
want, you can help out with this by writing unit tests for the issue and
submitting a patch.

In most cases his religious writing will be studied for many many years.
His politics will be forgotten very shortly.

I doubt it. The government simply doesn't have the means to control the fanatics who were among those persons rallying several days in a row after his death. Rabbis & other prestigious figures made overt statements that they would not allow their people to be drafted.

This is a LOT more serious than wishful thinking can solve.

I agree. Shas is not "politics as usual". They will continue to resist the
military draft and continue to study rather than work and continue to demand
extra privileges. And it's still the No. 1 party in Israel whose politicians
have served time in prison for monetary offenses.

I disagree. Olmert was prosecuted vigorously, but was found not guilty. The
evidence simply was not there. And the evidence was made public. I don't
think the Israeli courts are that corrupt.
