When running TWiki with mod_perl under RHEL5 A page load sometimes returns the error
TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

%ENV is aliased to another variable while running with -T switch

It seems the issue is the following code in LoginManager/Session.pm:

sub load {
    my $this = shift;
    local %ENV;

If I remove the local definition for %ENV the error does never show up. The people from FosWiki have noticed this too (see http://foswiki.org/Tasks/Item691 and http://trac.foswiki.org/changeset/1873) and removed the definition.

I suggest that the offending line is also removed but an impact analysis for that change may be necessary.

It looks like a safe change to remove the line.

Please go ahead and comment out the line, adding the bug item, such as:

# local %ENV; # TWikibug:Item6583 - commented out

-- TWiki:Main.PeterThoeny - 2010-09-29

Fix commited as described and ready for release in next minot update.

-- StefanWalter - 2010-09-30

Thanks. For bug fixes please keep trunk and latest branch in sync as much as possible. Could you make this change to TWiki-5.0 branch as well?

-- TWiki:Main.PeterThoeny - 2010-09-30

OK, I'm getting the hang of this. smile Change to TWikiRelease05x00 branch commited as well.
