@pingou Can you help here?

The error is:

Traceback (most recent call last):
  File "/usr/lib/python3.6/site-packages/pagure/ui/filters.py", line 846, in get_patch_stats
    output = pagure.lib.git.get_stats_patch(patch)
  File "/usr/lib/python3.6/site-packages/pagure/lib/git.py", line 2997, in get_stats_patch
    "Unable to properly retrieve the stats for this patch"
pagure.exceptions.PagureException: Unable to properly retrieve the stats for this patch

So there is something odd about the PR. If we know which fork/repo it came from,
it may be worth checking the commits diff there.

My fork and branch is: https://src.fedoraproject.org/fork/mikelo2/rpms/duplicity/tree/misc-changes

https://src.fedoraproject.org/fork/mikelo2/rpms/duplicity/c/3b6bbc52c97af4a2d6853127fa1dd99681872acd is the only commit in that branch, and it seems to load/diff ok...

Apart from the 3 modified files, there was another entry:

+ Subproject commit dbcd107e94afc5f2e6dde47a1de1e9a1d5fdc09b

i cloned the upstream repo inside the project and somehow it got committed for the PR.

Once I've removed I'm able to see the PR.

Thanks for your help @kevin, @mohanboddu & @pingou
