Comment 2 Zoltan Varga 2013-09-13 09:37:52 UTC
Is this reproducible ?
Comment 3 Jeffrey Stedfast 2013-09-13 11:23:26 UTC
I could probably repro it in Xamarin Studio if I re-enable the WebRequest.Abort() call (I've disabled it because I think that is inadvertently causing this?).
Comment 4 Zoltan Varga 2013-09-13 11:38:30 UTC
Its possible that the abort call truncates the compressed input to zlib, causing this crash.
Comment 5 João Matos 2014-02-14 12:01:19 UTC
I can look into this one but I need a way to reproduce it, saving the contents of the stream that's causing it would probably be enough to repro.
