@mlippautz -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

Not caused by my CL.

a.obzhirov@, Can you please look into this? Seems like we still need to merge this fix (https://bugs.chromium.org/p/chromium/issues/detail?id=676004#c4) to any other branch? Since CF has reported this crash after the above fix has been landed. 

Thank you!
