it permanently happens.

I just detect, it happens when i try to change from "Median cut" to "Neu Quant" and do not wait for calculating result about image compression press Save image, then app crash.

Image must me big: 8192x4096 pixels

I can't replicate this. I'm using a 4096x8192 png. Any other steps to reproduce? Thanks

Thanks for checking this. Unfortunately I haven't got more information, so let's file it under "hit by cosmic ray".
