I want to remind you all that the majority of Inkscape's code is not at all ready for multithreading. This save code, and all the code and data it needs for saving the document is certainly not thread safe. So the fix is to remove the _main_loop_run stuff, and just do the save right there and then (block on the save, and only continue when it is done).
