Description of problem:
Adding --verbose to a fedmod rpm2flatpak command line causes it to fail with Python AssertionError.  Dropping --verbose from the command line makes it succeed.


Version-Release number of selected component (if applicable):
fedmod-0.6.3-12.fc33.noarch


How reproducible:
always


Steps to Reproduce:
1. fedmod fetch-metadata
2. fedmod --verbose rpm2flatpak libreoffice


Actual results:
> ERROR:root:Unexpected exception: AssertionError()
