The gtk1 implementation uses get_xvisualinfo to retrieve an unspecific visual. The gtk2 implementation uses glXChooseVisual, which takes a filter. The default filter is to search for a double buffered, RGBA visual with stencil buffer. Maybe mesa does not provide such a visual. I added an exception, when no such visual was found. Either the defaults must be changed or a fall back mechanism is needed.
