Description of problem: Mozilla update from RH9 is broken How reproducible: 100% I upgraded my main box to the beta, the NFS mounted .mozilla was left untouched and starting mozilla produces random spew in a big window that looks like XUL errors. I've tried to pin down which files are problematic but its hard and the other mess like the locale bug make it very hard to tell the wood from the trees
Finally got to the bottom of it. The trigger is some kind of old old language pack either for en_UK (real English) or cy_GB and having had an old mozilla, I've marked it as "low" now because I can't duplicate this without third party old language packs.
Historic bug, closing
