It's a known issue, i will keep it open till it's fixed. Thanks for the report :)

@mciahdenn it seems i was mistaken (confused this issue with the fact that Pierre-Yves Chibon added milestones in issues on pagure at the same time). Are you still getting this error? Can you give us more info? (because, it is working in mine)

I'm getting exactly this error trying to do a test import of the FPC trac: https://fedorahosted.org/fpc into ssh://git@stg.pagure.io/tickets/packaging-committee.git

I'm not doing anything fancy. I am running pagure-importer 1.2.1 pulled from the copr instance since I have no luck figuring out how to actually run it from a git checkout.

Though, maybe that's because it makes checkouts to /tmp and I'm actually in /tmp. so, after a cd:

So, I don't know. At least the backtrace originally reported might just be due to the current directory. Maybe.

Fixed by #53
