Comment 5 for bug 827904

Daniel, thanks for the detailed steps to reproduce the problem consistently. You were right that the problem was indeed in the GTK frontend rather than in the backend. Specifically, the problem with the the hyper text widgets is the same as for the button widgets where handlers are called as many times as they are connected. So, handlers either need to be disconnected explicitly after being used or checked so that they are only connected once. This was done for buttons but not for hyper text widgets, so the attached branch should fix that problem.
