4. Close the Hangouts window.
5. Install the ADP extension (​https://chrome.google.com/webstore/deta ... fddb?hl=en)
6. Open the Hangouts extension => see that assets no longer load)
7. Disable the ADP extension (on chrome://extensions/).

Workaround

Whitelisting talkgadget.google.com will cause it to function properly again.

There are additional investigations done by @ricky in the forums: ​https://adblockplus.org/forum/viewtopic.php?f=11&t=22080&sid=e59dbb36bf5fd4ef1136e27d51df8d86

Just to clarify what I said a little bit, the cause of the issue seems to be that in the recent dev chrome builds, extension windows no longer define window.url (previously, window.url was a chrome:// URL). A bunch of adblock plus code seems to assume that window.url is defined. The function that crashed in this case was isFrameWhitelisted, but there may be more places in the code where undefined window.url might need to be handled.

It looks like this issue may be a duplicate of ticket #178.
