I tried to switch back to 0.7.5 after the above bug, but the
same error appeared. I had to trow away the mysql database
and put back the backup to get roundup to work again. When
it worked again with 0.7.5, I switched again to 0.7.7. The
*TypeError* was there again. Switched back to 0.7.5, again a
*TypeError*. Restored the mysql database, 0.7.5 worked fine
again. I tried this 4 times, each time with the same
results. I also tested it between 0.7.6 and 0.7.7. Release
0.7.6 works ok, but gave a *TypeError* after I tried to use
0.7.7. So same behaviour as between 0.7.5 and 0.7.7.
It really looks like 0.7.7 corrupts the mysql database.
Maybe it would be whise to remove 0.7.7 from the download
page until this problem has been investigated and fixed.

FYI: This was the test setup:
Server: Windows NT 4 - SP6a
Python: 2.3.2
Python-Win-ext: 23 build 200
Python-MySQL: 0.9.2
MySQL: 4.0.18
