When requesting the component details in Bugzilla 5.0, the following error comes:

RuntimeError: This bugzilla version does not support fetching component details.

The related code is:

def _getcomponentsdetails(self, product):
# Originally this was a RH extension getProdCompDetails
# Upstream support has been available since 4.2
if not self._check_version(4, 2):
raise RuntimeError("This bugzilla version does not support "
"fetching component details.")

However, when omitting this check, the function seems to be supported.
