I can't reproduce this. The comment on the task works fine for me.
Getting a second opinion.
Can't reproduce this on my upgraded desk.
Thanks

Probably a local helpdesk issue w/ the 'comment' table.
After a few more reports of problems with comments I would recommend the users check there comment table and make sure that there comment.id is set to auto-increment.

Reopened because there have been several reports of the 'comment' table not having an autoincrement.
I pushed some tweaks for us to observe during future upgrades.
