Segfault when starting SEQ

[someguy]

I got SEQ to compile and install properly, but when I run it, I immediately get this:

ShowEQ 4.0.0, released under the GPL.
Using config file '/usr/local/share/showeq/showeq.conf'
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "RENDER" missing on display ":0.0".
Loading filters from 'usr/local/share/showeq/filters.conf'
Initializing Packet Capture Thread:
Filtering packets on device 192.168.0.101, searching for EQ client...
Segmentation fault (core dumped)

Any ideas/suggestions?
