Re: occur error when use GdkPixbuf savev method in gjs

["Alan Knowles" <alan akbkhome com>]

Check what the introspection data for GdkPixbuf savev is declared as.

I suspect it's broken (needs fixing upstream)

The last two arguments are supposed to be arrays and defined like this.
<array c:type="gchar**">
 <type name="utf8"/>
</array>

the copy I have for that file (is a bit old so it might have been fixed) shows this.
<parameter name="option_keys" transfer-ownership="none">
            <doc xml:whitespace="preserve">name of options to set, %NULL-terminated</doc>
            <type name="utf8" c:type="char**"/>
          </parameter>

If the gir is correct the correct syntax is probably
pb.savev("screenshot.jpg", "jpeg", [], []);
