"Unrecognised line" error from EmailParser

RT Users
1

When I try to add a new Requestor to a ticket, I’m getting:

Unrecognised line: tony@tmtm.com at
/home/customers/sites/rt//lib/RT/EmailParser.pm line 404

This is coming from Mail::Address, but I can’t replicate the problem
outside of RT at all. A simple script which calls the method in
Mail::Address, or even the method in RT::EmailParser works just fine.

The full trace is below.

Anyone seen anything like this before?

Thanks,

Tony

Anyone seen anything like this before?
It’s caused by a utf8 / regex interaction bug in perl 5.8.0. A
workaround has been checked into the subversion repository of RT; either
upgrade perl, use rt from subversion, or apply the following patch.

Excellent.

I’ll try to get an upgrade done (although I’m not too hopeful). I’ve
just applied this patch by hand.

Thanks for the quick response.

I have applied the following patch to my RT installation, but am still
getting the following error:

I’m running perl-5.8.0 on RHEL3, which others seem to have working…
Anyone have any thoughts as to why this error remains?
Is there a way to test that the utf8 flag is actually being turned off,
and print a message to STDERR?

Please read FAQ. You want upgrade your perl.

I had this problem as well and by upgrading to perl 5.8.5 the problem went
away.-----Original Message-----
