Comment 69 for bug 26436

Hi there,

I had a similar error: gtkmozembed hung the whole application, when accessing certain sites with flash-animations.
After almost a day, the following line found to be absolute incompatible with gtkmozembed and flash:
gtk.gdk.threads_init()
Seems to be a threading problem: This line was garbage in my Script and did not have any purpose. My fault, but kind of strange...

After all: Threading and gtkmozembed work, when no flash plugin is installed for firefox.

Hope, this is useful for someone.
