I've traced the working Firefox on the same URL (full trace attached).

The scenario was following:

1) it tried to connect with:
  enableSSL2 = 0,
  enableSSL3 = 1,
  enableTLS = 1,
  v2CompatibleHello = 0,

2) then it tried to connect with:
  enableSSL2 = 0,
  enableSSL3 = 1,
  enableTLS = 0,
  v2CompatibleHello = 1,

It looks like sort of workaround for some buggy servers to me, not yet looked
at the source code. Maybe we want to dig it out of Firefox and put it to
libcurl. Any ideas?
