Description of problem:
Exception raised during srpm import during build using Mock SCM
Build failed whenever rebuild / resubmit to build using Mock SCM
which fetch the latest source from github master branch and build.

if we execute the build using source rpm it passes.

How reproducible:
Most of the time.
Some time the build passes.

Actual results:
