which permission should I declare？

*edit:*

I found a similar problem in [WebView java.lang.SecurityException: No permission to modify given thread](https://stackoverflow.com/questions/11025182/webview-java-lang-securityexception-no-permission-to-modify-given-thread)

The Answer say "It's cyanogen's fault." 

However, in the thread <http://code.google.com/p/cyanogenmod/issues/detail?id=5656&thanks=5656&ts=1341224425>,cm menbers seem to deny it's CM's bug

Above all, my question is:
**How to fix it from my app?**
