|The stupid question is the question not asked|
I encountered the problem while implementing content compression in Maplat. It happened while while handling forms and downloading dynamically created XML files.
The client was running on Windows with ActivePerl. There *may* have been i misconfiguration or missing package. But i have since reinstalled the windows development server, so i'll have to recreate the circumstances and try if i can come up with a small test system.
It may have been a bug in Maplat as well. But then again it only happened with WWW::Mechanize.
Do you have Compress::Zlib installed? That is - from what i can tell with only a glance at the source - the main difference between WWW::Mechanize and WWW::Mechanize::GZip. The former uses Compress::Zlib when available while the later requires it to be installed.
That said, i'll try to recreate the problem but it might take some time. I'm currently in the middle of preparing a big server upgrade (nice monks are allowed to upgrade to Postgres 9.x while naughty ones have to keep using flat files).
Don't use '#ff0000':
use Acme::AutoColor; my $redcolor = RED();
