bug 264868 - problem with emailregexp / emailsuffix in 2.18rc3

[Andrew Kitchen]

Hello Everyone,

I recently upgraded a test installation of bugzilla from 2.18rc2 to
2.18rc3 on windows.  My 2.18rc2 system works great but we have wanted to
keep current with 2.18 to pick up fixes and enhancements that have come
through in the latest release candidate.

I set up an unmodified copy of 2.18rc3, ran checksetup.pl twice and made
some edits in my editparams.cgi, most notably, setting emailregexp to
^[^@]+$ and emailsuffix to @mydomain.com, and turning on qacontact.
This all worked fine for me in rc2, but in rc3 when I view a bug the
email suffixes are appended to qacontact in show_bug.cgi, and therefore
user matching fails and I cannot submit changes to a bug until I go back
and strip @mydomain.com from the usernames in Qacontact and assignee.
This makes certain state changes impossible (such as resolving the bug)
since the only way to change the assignee (or edit their email address)
is to reassign the bug (from 'me at mydomain.com' to 'me').  

A search of BMO turned up this bug
https://bugzilla.mozilla.org/show_bug.cgi?id=264868 
(Bug 264868 - show_bug.cgi should honour 'emailsuffix' in 'Reassign bug
to' field) which seems to describe the problem.  I voted for this bug
after mistakenly setting the blocking2.18 flag to '+'.  I reset the flag
to '?' but I would consider this to be a blocker as enabling these
features makes the system unusable.  I'll try to take a stab at testing
the proposed patch.

thanks, and kind regards,

-Andrew
