It appears that category/portname matching is case sensitive, as seen in bug 204838 which did not result in assignment to MAINTAINER (me) Update auto-assigner summary matching to be case-insensitive
(Snatching bug from mmokhi@) Fixed in https://github.com/gonzoua/bugzilla/commit/947088b8ef1657dce4d4d84cb6b3d67332cc0ee3 Fix forces category part of port name to be lower case because all categories are lower case. Actual port name can be mixed case and should be case-sensitive
