GUI without tilts crashes

[svvenkatakrishnan]

When no tilts are present, by mistake I hit reconstruct, code crashed. Can we exit more gracefully out of it?

Which GUI is this? I thought I had a sanity check in there, but maybe not.

I have tried both GUIs with single slice and full reconstructions and all times with both GUIs I get an error dialog box that says I do not have any tilt angles and stops.

Great. Thanks.
