unhandled exception

[dieterdreist]

I uploaded what I mapped.
The * besides the name still indicated that I had unsaved changes. I tried to reupload: "no changes to upload". I tried to delete the data-layer: "you have unsaved changes" (only upload, because I didn't save locally). I clicked on "upload, then delete layer". -> unhandled exception
