EVALUATION

So 6547593 was about the name of the month being localized in the release string, which can be fixed by not using a month name but a month number. The other part of the version string is the username, which just needs to be filtered to only include alnum characters.

EVALUATION

Could be a dup of 6547593
                                     

EVALUATION

There is some concern that maybe the solution should involve native2ascii so that the username characters are not turned into '.' but maybe something that could be transformed back into the real username?  Just a thought.
