Hey there.

I found a bug in ZNC, which looks to exist on 1.6.3-rc1, 1.6.3 and 1.7.*-git.

I was doing /znc *shell grep '(some|nicks)' ~/moddata/log/jeda/freenode/*/*.log on my ZNC, and I disconnected which made ZNC crash. By the debug I did, it's a "Broken pipe" error.

This issue is invalid as you didn't follow http://wiki.znc.in/Debugging ((gdb) handle SIGPIPE nostop).

SIGPIPE is not the issue.

As wiki data was wrong, I fixed it. Looks like it is a SEGFAULT.
