Unexpected Exeption on checking/unckecking upload or save on deleting a layer

[anonymous]

What steps will reproduce the problem?

1. Download OSM-Data into layer
2. change something
3. delete layer
4. check or uncheck the upload and/or save checkbox

What is the expected result?

upload or save

What happens instead?

It seem that both works fine – uploading and saving. But it throws the exeption first.

Please provide any additional information below. Attach a screenshot if
possible.
