Yes, but there's still something wrong. An application error, (such as
passing a cairo_format_t instead of a cairo_content_t), should never
cause an assertion. The assertion triggering is intended to indicate
that there is some internal error within cairo itself.

For example, in the case of cairo_surface_create_similar, the
CAIRO_CONTENT_VALID check should trigger before it ever gets the
chance to get to the assertion.

So I would still like to hear more specifics (eg. stack trace leading
to assertion) from users who are seeing this problem so that we can
fix whatever bug it is that cairo has.
