When Harry wants to withdraw money for Christmas presents Dumbledore outright says he doesn't want Harry to have "access to large amounts of gold with which to upset the game board" I'd say he's as likely to memory charm Harry's gold/silver scheme as Quirrell.
In fact (on a more tangential note) who says that isn't exactly what Flamel is doing? Exchanging silver for gold in such quantities as to make himself rich but not terribly upset Muggle economics. Maybe Flamel is the occlumency teacher, memory charming anyone who comes up with the same plan.
Well, Flamel could just use the philosopher's stone to transmute base metals to gold. So I doubt he would bother with commodity-trading. But, yeah, Dumbledore should be a suspect at this point, though I assign a low probability to him being behind this. Dumbledore does not want Harry to be indebted to Malfoy (unless MoR Dumbledore is secretly completely different from canon Dumbledore), and so he would not hinder Harry in his quest to pay off the debt quickly.
