Hi,

I encountered a problem yesterday that all layout tests crashed on Mac Snow Leopard.

DumpRenderTree produces the following output when run from command line:

$ time ./DumpRenderTree

===============================

I tried to remove /Library/Internet Plug-Ins/JavaPluginCocoa.bundle, then DumpRenderTree worked.

Anyone has encountered the same problem and/or has better solution?

BTW, why is crash reporting for DumpRenderTree so slow (3.5 minutes)?

Thanks,
