Kai, you're triaging a similar report - can you please handle this one too? Please duplicate if necessary. Thanks.

I actually let this run in the background earlier - I just checked on it, and it doesn't seem to have reproduced:

New crash type: Direct-leak
New crash state:
  FcPatternObjectInsertElt
  FcPatternObjectAddWithBinding
  FcPatternAppend

Original crash type: Null-dereference READ
Original crash state:
  width
  bool blink::WebGLRenderingContextBase::ValidateTexImageSubRectangle<blink::Image>
  blink::WebGLRenderingContextBase::TexImageImpl

This looks extremely similar to the other report, so I'm going to mark as duplicate.
