FileType plugins: Crash on 'Canceling' dialog

[midora]

If you are pressing Escape while the "Canceling' dialog of a save operation is visible then Paint.NET will crash.

 

This may happen if you are just pressing two times Escape in a Save Configuration dialog while the preview is calculated in the background.

BTW: Clicking the close button of the Save Configuration dialog while the preview is calculated does not show a canceling dialog. The dialog closes immediately but the save operation continues invisible in the background.

 

The canceling dialog is only visible after clicking the cancel button or pressing escape.

Interesting ... I've been wondering what causes this for a long time. I've been getting crash logs for this for awhile but no one ever told me what caused it for them ...
