E-mail interface may create bugs having no bug tasks

[Björn Tillenius]

As seen in OOPS-1298A350, we have some bugs in the database having no bug tasks.

< BjornT> kiko: all the descriptions have e-mail commands, so i think.
          it's quite safe to assume it's the e-mail interface that is to.
          blame
< BjornT> kiko: i don't think it's something that we need to fix for the.
          rollout; looks like it's been like this for a long time. i.
          think i know what's wrong, so we could see if we can fix it.
          next cycle, shouldn't be too hard.
< kiko> BjornT, cool, but we will need something to fix the data up. what.
        do you think is broken?
< BjornT> kiko: that's easy: DELETE FROM Bug WHERE Bug.id IN.
          (<query-above>);
< BjornT> kiko: the problem is how we do error handling in the e-mail.
          interface. quite a while ago it got changed to not require all.
          commands to succeed, but instead let some succeed, and then.
          send error notifications for the failing ones
< kiko> BjornT, ah, so in this case it is failing in a critical part of.
        the process
< BjornT> kiko: when doing that, some commits are made to ensure that we.
          can roll back on failures, but it looks like we're doing a.
          commit when we shouldn't (right after creating an empty bug)
< BjornT> kiko: yes, nothing is linked to the bug. it fails before the.
          bug task is created.
