Custom File Menu Refresh Crash

[robwiese149]

Hey. 

So I'm creating a custom file menu inside maya and have successfully done this reading a yaml file to loop through and create all the menus/submenus/menuItems. A python file/function is called within the userSetup.py file just fine and the menu shows up and is working when launching maya. However, I have one menuItem button I want to use to refresh this custom menu if I update the yaml file with Maya already open.

I created a python function to do just this that essentially will delete the custom menu and all items underneath it and then run the original createMenu function to re-create the menu with the updated yaml file. To my surprise, when I launch the refresh menu button, it runs through the full code (all lines are executed without error) and then Maya crashes. No idea what is going on. If my code is executing all the way through with zero error, why would Maya crash afterwards?

I went and found Maya's crash log and here's the most recent crash log I got:

If anybody has a specific way to refresh a custom maya file menu, I would much appreciate seeing how that's done without crashing maya.

Thanks for the help!

I can only suspect your code is doing something it shouldn't, probably when you delete (depending on how you're doing it).

The crash is Qt based, so nothing related to reading the file.

If you can post the code or a snippet to reproduce it?
