The segfault is thrown in "int GLContext::InitSGIX()" (GLContext.cc:462), when 
configs is accessed after
configs = glXChooseFBConfigSGIX(::display, 0, attrList, &config_count);
has resulted in no configuration.
I wonder why InitSGIX is invoked although rendermethod has been set to AUTO or 
GLX. It seems that the tag is being ignored.
