Renaming repos imported from GitHub doesn't work

Description of the problem

I'm trying to import a repo from GitHub to GitLab.com. I already have a repo with the same name at GitLab, so I tried to rename it while importing using the appropriate field (see attached image). Unfortunately, despite this the job fails.

Which Group/Project (with full path) is experiencing the issue?

https://gitlab.com/import/github/status

Approximate date/time when the error occurred.

2/25/17 9:30pm PST

I was importing other repos, all but this one worked fine
