Clicking "layout" in the fast-preview causes hang.

[rew]

Trying to reproduce another bug, I seem to be able to cause a (100% CPU) hang in Hugin when I click "layout" in the fast-layout window.

The project consists of 45 images of an 3-stack HDR blend. The Fast preview window looks useable. Hugin generates a nice HDR image, but clicking "layout" causes hugin to start processing something, and stops refreshing the screen. Whatever it is doing, it should not stop refreshing the screen. Maybe it is doing something that will end, but I didn't have the patience to wait.

PTO attached.

Can someone (else) reproduce? With the current version?

I have seen this some time ago, the layout mode was unusable (appeared to hang forever) with a project with many photos.

I created dummy photos for your project and loaded it into Hugin, the Layout tab displays immediately and is responsive.

OK. I tried it with the original images, and the "tip" version of hugin. Seems fixed. -> Fix released.

(I tried it with the .pto I found in the directory with my images, as well as the one I saved here with this bug, and both will fire up the fast preview window just fine. Lots has changed since I last saw the fast preview, so it's evident changes have been made).
