My weekly cronjobs ("deep-check --repair" and "backup") started failing two days ago. Upgrading to the latest Debian package (allmydata-tahoe_1.4.1-r3916_all.deb) did not help, the problem persists.

Example output from the cli (this is from allmydata-tahoe_1.4.1_all.deb, ie. pre-update):

$ tahoe deep-check --repair media:
ERROR: AttributeError(MutableFileNode instance has no attribute '_writekey')
[Failure instance: Traceback: <type 'exceptions.AttributeError'>: MutableFileNode instance has no attribute '_writekey'

/usr/lib/python2.5/site-packages/allmydata/mutable/filenode.py:172:get_writekey

Output from allmydata-tahoe_1.4.1-r3916_all.deb is identical, up to the line numbers.

Running "deepcheck-and-repair" from the WUI results in the same exception, yet no incident report is created. I'll attach the HTML output of the result page (after clicking "reload").

This is probably another instance of #625, unfortunately.

It's clear from the traceback that this is a duplicate of #625.
