After trying with a different branch, it looks like the issue is due to me force-pushing the pull request origin (rather than with github or with slashes in the branchname or something). However, given that pagure refued the pull due to an unsigned commit, I'm not sure what else I could have done...

Is this something you can easily reproduce? I do not remember getting an email for it and if we can reproduce it, I'd like to check the logs for the error.

Yup, reproducability appares to be 100%; I just did it again with the
bug/151 branch of gssproxy.

To be clear:
- create branch with commit that is unsigned
- attempt to open pull request
- it fails because it's not signed
- force-push a signed commit
- attempt to open pull request again
- receive error 500

Thanks!
