xmms_remote_playlist_clear/xmms_remote_playlist_delete freezes xmms

Hi.
I'm writing a general plugin at the moment (using xmms 1.2.10), but
whenever i try to call xmms_remote_playlist_clear or
xmms_remote_playlist_delete xmms freezes.  Below is the most vanilla
code i could come up with to clear the playlist (which freezes):-

#include <stdio.h>
#include <xmms/xmmsctrl.h>
#include <xmms/plugin.h>

static void blah_init(void);

GeneralPlugin blah =
{
	NULL,
	NULL,
	-1,
	"_Blah",
	blah_init,
	NULL,
	NULL,
	NULL,
};

GeneralPlugin *get_gplugin_info(void)
{
	return (&blah);
}

void blah_init(void)
{
	//check that it gets here
	printf("play0:%s\n",xmms_remote_get_playlist_file(blah.xmms_session,0));

	xmms_remote_playlist_clear (blah.xmms_session);
	return;
}

Anyone care to tell me why i'm stupid?

Cheers
