i don't think so, the game is very good and of an excellent quality, if there were any glitches, i would assume they would be impossible to find. very few glitches have been found on the pokemon games, as games become more advanced glitches become harder and harder to find so my overall answer is.... no ;D
no i played the game and there were none!
