Hello,
 I tried to reproduce what you mention I don't see any issue in gnutls
negotiating with the server. You can also see that by checking the
wireshark log, as well as running wine while GNUTLS_DEBUG_LEVEL is set
to something more than 6. It seems like the application (or wine) is in
an infinite loop creating a client hello.
I'd suggest to try to debug it further with the wine people, and if the
issue concludes that gnutls fails to talk to some server then bring that
here. As it is now I don't see any such issue and there is very little
that can be done by gnutls for the issue you see.

You could also try comparing the wireshark logs from the version that
works with the other that doesn't and try to spot the differences.

regards,
Nikos
