Oops, this should have gone to webkit-dev. Sorry. (But don't hesitate to answer if you know how to fix the problem!)

Hi everyone,
I'm not sure if this is the right place for this question, but I'll gladly change mailing lists if it isn't.

I'm working on a Dashboard widget with a multi-threaded Cocoa plugin. The plugin seems to be working just fine, but I'm getting an occasional (frequent but inconsistent) crash that appears to indicate a bug in WebKit:
======================================================
Exception:  EXC_BAD_ACCESS (0x0001)

The crash is preceded by incorrect width of displayed divs, disappearing elements, or both. Does this seem to you to be a WebKit bug, or is it more likely to be a problem with my code?
