Description
I had downloaded a few regions to a data layer (to fix validation errors) and committed twice to the same changeset that I left open. Then, I right-clicked the data layer in the list of layers and selected the menu item with the trash bin symbol, to delete the layer. The map display was replaced by the startup splash screen, and I got the exception window. The debug information is as follows:
