I just tried it and it does not work.
I have to change it a little:

Index: libs/libmythtv/NuppelVideoPlayer.cpp
--- libs/libmythtv/NuppelVideoPlayer.cpp        (revision 10888)
+++ libs/libmythtv/NuppelVideoPlayer.cpp        (working copy)
@@ -1574,11 +1574,11 @@
     /* If subtitles are enabled before the teletext menu was displayed,
re-enabled them */
     if (prevTextDisplayMode & kDisplayAllCaptions) {
         textDisplayMode = prevTextDisplayMode;
+        EnableCaptions(textDisplayMode, false);
     else {
         textDisplayMode = kDisplayNone;

 void NuppelVideoPlayer::ResetTeletext(void)

and then it works with dvb-teletext subtitles. (with my sample streams)
