Bug report - Changing sequence settings to 1280x720 causes crash and corrupted project file

Hello,

I am working in a project file with lots of sequences artworked to different output specs.

When duplicating a sequence then changing the dimensions to 1280x720 the project crashes and then the project file becomes damaged.

I am able to recover the last save by re-importing it to a blank project. But repeating the steps above produces the same crash/damage each time.

Thanks!

Neil
