Crash when attempting to import a bitmap image if no image is selected

If you go to File>Import>Bitmap Image and click on a folder name and then click the "Choose" button, playsci win32-0.9.6 crashes to desktop. I would include my console log but it's blank for some reason.

Attempting to Import any other file format without selecting a file leads to a "Failed to Import" message, as it should.

Fixed in 0.9.7
