This looks like a BTextView problem independent of WebKit. Can it be reproduced?

Component: Applications/WebPositive → Kits/Interface Kit
Owner: changed from pulkomandy to nobody
Summary: [WebPositive] crashes with RealCharAt: invalid index supplied → [Interface Kit] BTextView crashes with RealCharAt: invalid index supplied

Not reproducible for now.
