This is in reference to Chromium bug: http://code.google.com/p/chromium/issues/detail?id=88038 A patch soon to land in Chromium will introduce a non-crashing version of the canvas factory function CreateBitmapCanvas. The constructor of ImageBuffer in ImageBufferSkia.cpp must be modified to use the non-crashing version, and gracefully fail when it returns NULL.
