We have a similar warning already:
http://source.winehq.org/git/wine.git/?a=blob;f=dlls/ws2_32/tests/sock.c#l2454

Surely there's some warning we can agree on...currently, it doesn't
give the user any hint of what's wrong. As far as they can tell, it is
solely a Wine problem, not their system being misconfigured. If a user
sees "no Verisign certificate", they'd be more likely to investigate
why that is, and fix it (or, if they are installed, file a bug).

Silent application failures are probably worse...
