While not precisely the same crash, deb #596155 and fdo #28882 bugs are
all faulting on the same bit of code.  create_bits_picture() attempts to
instantiate an image via a call to pixman_image_create_bits(), however
that call can fail under a variety of circumstances and return a NULL
image pointer.  This is then passed unchecked to
pixman_image_set_has_client_clip() where it is dereferenced and
generates a seg fault as a result.
