Hugin 2013.0 doesn't open my document at launch so it doesn't crash. Is this a bug or a solution? Hugin still crashes most of the time if: Hugin is already running, the Fast Preview window is the front window. I double click my document in the Finder, one of the files can't be found. Hugin crashes after I select the file or click on the Cancel button of the Open dialog.

It looks like the Fast Preview window is too fast and uses a file before it is opened. This can be provoked by renaming a file but could also happen if all files exist (in version 2011.4.0). I'm still using OS X 10.6.8 iMac7,1, Intel Core 2 Duo, 2.4 GHz, 4 GB I usually use TIFF images, 16 bit gray and tried different image formats like 8 bit gray, 32 bit color and jpeg.
