Segfault on new client connect

[tehcyx]

There's a segfault in client.c line 163 on the strncopy that I found by using gdb:

[New Thread 0x7f93a2d20700 (LWP 17294)]

Program received signal SIGSEGV, Segmentation fault.

Reproduce with:

1. Connect client (sometimes happens here already)
2. If your client supports it use 'reconnect' functionality (have always gotten segfault here now)
