No, because it asserts that plist->type should be equal to WPLDictionary, without checking for a NULL plist argument. > This code is from the WINGs source that comes with windowmaker. OK, first of all I don't run WindowMaker so this is not going to be up my alley, but I can guess, and maybe get you going a little further: It seems that plist =3D=3D NULL. If you type 'frame 1' in gdb after the bt you should get the line where WMGetFromPLDictionary is called, this is at menu.c:2720 as gdb says. The NULL pointer seems to be scr->session_state, in other words, there doesn't seem to be a session state loaded. My rough guess is that something in your .wmaker startup dir is screwed. Have you tried to remove that to test if it works then? Otherwise you need to trace the code and try to figure out why scr->session_state isn't being initialized like it should. > Any idea what could be causing this? Other than the above hints, no, sorry. You'll probably get better help from the wmaker mailing list. --Stijn --=20 "Computer games don't affect kids; I mean if Pac-Man affected us as kids, we'd all be running around in darkened rooms, munching magic pills and listening to repetitive electronic music." -- Kristian Wilson, Nintendo, Inc., 1989 --UugvWAfsgieZRqgk Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.7 (FreeBSD) iD8DBQE9v5ZzY3r/tLQmfWcRAjCCAJ9QaEliJInDwaRRcqrO/zhUPVQ6VgCff064 N9c2n9Yzqgh5OoKP2w0BQdI= =WaS6 -----END PGP SIGNATURE----- --UugvWAfsgieZRqgk-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
