I learned during the fixing of #1100848[0] that some of the attributes for an uploaded erratum don't have the same types as the synchronized versions. The only attribute I know this for sure about is "pushcount". For an uploaded erratum, pushcount will be an integer, but for a sync'd erratum it will be a string (of an integer).

We needed to fix [0] quickly so we went for making sure we only have strings to ElementTree. I believe the correct fix is to make sure we are consistent about the types that land in our database between synchronizing errata and uploading them. I personally believe that pushcount should be an int in the database, so for that case we should fix the synchronization code.

I set the severity to low because I cannot think of a use case that this would cause an issue for.
