I have several commits that have been importing for a while now. All three of them are empty commits and crash whichever daemon grabs the task with the following stacktrace:
```

All three commits are in different repositories. They're empty commits created just to be tagged as a new version release. Another peculiar thing is that when the task crashes, the failure count for the task is not incremented.
