x11/xvkbd broken on 9.1? Requires ~/.Xdefaults to be present

[ecd]

x11/xvkbd seems to give a coredump for even basic usage (e.g., no command line arguments).

I'm using a fairly recent version of 9.1-STABLE.

Interestingly, truss shows something interesting..

[ecd@qk ~]$ truss xvkbd
...
open("/home/ecd/.Xdefaults",O_RDONLY,00)         ERR#2 'No such file or directory'
SIGNAL 11 (SIGSEGV)
process exit, rval = 0
[ecd@qk ~]$ touch ~/.Xdefaults
[ecd@qk ~]$ xvkbd # now it seems to work

I haven't had time to look too much into this. Could someone help me confirm this is broken? I did not see anything with my searches. Thanks.
