Crash in SSL

[DarthGandalf]

I was playing with ZNC certificates and managed to crash KVIrc 6710797 by connecting it to it while znc.pem is an empty file

The crash happened when I clicked the "connect" button on toolbar in the context which was previously connected to that ZNC instance; at the moment of that click it wasn't connected.

Here's log from ZNC:

I suppose ZNC closed the socket by seeing incorrect certificate, but KVIrc shouldn't crash by that
