I submitted the bug report from within the plugin, itself. There's a "Support" link I used to report the issue. I'm confident the plugin author is aware of this specific issue because Mr Townes responded to my bug report via e-mail and asked for more information. :)
I don't know if Mr Townes did any investigation into the issue since I told him the upgrade to W3TC 0.9.2.11 addressed the issue but at least her responded to my bug report.
So, if you haven't filed a bug report yet, you might want to consider doing so. Or, maybe he'll see this thread and take another look at the bug report I filed.
Peace...
