Re: Decompressing a string with zlib problems

[Jochem Maas <jochem@xxxxxxxxxxxxx>]

you have another problem - in that all these very specific strings
that you are posting could very well be being mangled in someway
because of the mail transport. in fact I doubt it comes thru in
way that makes it testable at all.

it doesn't help that googling for 'dcomzlib' brings up your own posts
as the first results. not very helpful.

interesting problem - sorry I can't help
