The culprit would seem to be this bit of devX11.c
1302 xtdpy = XtOpenDisplay(app_con, NULL, "r_x11",
"R_x11",
1303 NULL, 0, &zero, NULL);
1304 toplevel = XtAppCreateShell(NULL, "R_x11",
The 2nd arg to XtOpenDisplay is listed as display_string, so passing a
NULL here seems like trouble when the default ways of finding the
display do not work.
Looks like a fix is to insert p instead of NULL. (Tested rudimentarily.)
