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?
