XtConvertAndStore() error

[Russell Shaw]

Hi,
In two unrelated X programs, XtConvertAndStore() fails saying:

    Warning: Missing charsets in String to FontSet conversion
    Warning: Unable to load any usable fontset
    Error: Couldn't find per display information


This is the point of failure in one of them:


gui_init_tooltip_font()
{
     XrmValue from, to;

     from.addr = (char *)gui.rsrc_tooltip_font_name;
     from.size = strlen(from.addr);
     to.addr = (XtPointer)&gui.tooltip_fontset;
     to.size = sizeof(XFontSet);

     if (XtConvertAndStore(vimShell, XtRString, &from, XtRFontSet, &to) == False)
     {
         /* Failed. What to do? */
     }
}
#endif


(gdb) print from.addr
$2 = 0x8181353 "XtDefaultFontSet"

(gdb) print from.size
$7 = 16

(gdb) print to.addr
$5 = 0x81a2b70 ""

(gdb) print to.size
$6 = 4


I'm using X.org on debian-sid.
