```
error: bogus commit object 0000000000000000000000000000000000000000
fatal: corrupt commit
```

When trying to update an existing CL and does not do anything

or 

```
Error after CL description prompt -- saving description to /usr/local/google/home/dgn/.git_cl_description_backup

Created|Updated 0 issues on Gerrit, but only 1 expected.
```

Which fails although it successfully creates the CL. 

I'm not sure what to file it against. John could you please help with triaging?
