xtermset core dumps

I installed beta3 from cd then installed xtermset from ports, it crashes if 
i try and use it:

xtermset -T $PWD

using gdb on the core file shows the following stack trace:

#0 0x080495ca in term_last () at term.c:66
#1 0x08049635 in term_new (comp_type=-791621424, name=0xbfbfe471 "rxvt", 
len=4) at term.c:39
#2 0x08049862 in term_loadall () at term.c:144
#3 0x08048e4b in main (argc=3, argv=0xbfbfe934) at xtermset.c:65

line 66 says:

n = n->next

if I do:

p n->next

in gdb it gives:

Cannot access memory at address 0xd0d0d1d4

I can't try it on current because my buildworld fails (See other post).

regards
