Hi,
there is SIGSEGV happens in qconf.cc:995
str += print_filter(sym->name);
but sym points to 0x1. To reproduce the error just do:
1) make xconfig (with Options->Show Debug Info unchecked)
2) go to Networking->Networking Options->Network packet filtering framework (Netfilter)->
Network packet filtering framework (Netfilter) and the line "<| .." must be selected
then just turn on Options->Show Debug info menu and you'll get:
make[1]: *** [xconfig] Segmentation fault
make: *** [xconfig] Error 2
gdb shows:
Program received signal SIGSEGV, Segmentation fault.

(gdb) p sym
$20 = (symbol *) 0x1
I'm investigating this...
