I attached this to ticket #1118.  It's a small log and captures both
problems, the assert and the failure to place shares.  These problems seem
to be related, because I can reliably reproduce the share placement error
after hitting the assert error.

I've only captured the log from the unix machine that was performing the
tahoe backup.  I couldn't get flogtool running on Windows XP ("ImportError:
No module named run_flogtool") and didn't even try it on the other Windows
flavors.  If needed, I could try using the Report an Incident method for
those nodes, but I'm assuming the log from the node running the backup is
the important one.

Here are the last few lines of the flogtool console output showing the
failed upload.  Looks one node already has two shares?  Weird.
