Crash when closing DAW or Standalone

[Casey Kolb]

My plugin will occasionally show a crash report when closing the standalone or a DAW. I haven't been able to get to the root of what's causing it, but I'm attaching the symbolicated crash report below. The last function call in the trace stack is cleanJavascriptObjects so I think it's trying to access something which no longer exists at shutdown. Anyone else run into this?
