Testing Web Raid's new 5x5 levels

Okay. My first game that consists only of the new kind of level. I enter my previously favorite level "tythe" (Wikipedia); at least the monsters there are not too hard.

... And I get a Java exception immediately... This doesn't happen with other levels. The culprit is a level below tythe that is created from the en.wikipedia.org/wiki/Mumbai which apparently only has a single english word, "an" (but you can see plenty of English in Firefox...). Do the hindi characters in there mess up the game?
