New submission from Antoine Pitrou <[email protected]>:
The buildslaves "i386 Ubuntu" have been exhibiting some strange behaviour for
some time now:
======================================================================

Matthias, can you give us more information about the system setup on these
buildbots? It seems its OpenSSL library refuses to allocate any SSL context for
the SSL v2 protocol. Is it some kind of patch added by the Ubuntu OpenSSL
maintainers in order to disable SSLv2 entirely?
