It's wierd, but none that I've heard of. The thing with E-6000 is that it stays a little flexible after it has cured, unlike most glues that become hard, and therefore brittle. Also, with E6000, you can remove it, if you're careful, and redo what you did in case you mess up.
There are some sites in Sweden that sell E-6000 but with the dollar as low as it is now, it's cheaper to order it from the states.
