Can you please attach one such complex drawing that causes a crash? Or even better, remove half of the objects and check whether you still have a crash. If not, remove the other half and see if you now have a crash. Try get a fairly simple image that still crashes.

This is an assertion. I don't think it has anything with the win-print test code to do. Somehow Inkscape asks cairo to use an operation that is not supported on the win32 printing surface. Hopefully Inkscape does not need to know what operations are supported on each back-end, cairo will simply do the best possible behind the scene (such as using rasterization if needed).

Can you also try save as "Postscript via Cairo" to see what happens? To try the pdf-backend you need to activate it in extensions/init.c (look for a if (0) statement).
