Ubuntu 18.04: kstars clean install from git source.

Hi everyone
Not having much luck with fitsviewer. There's a crash after uploading an image from the camera, an eos450. Worked ok for 29 captures then:
Maybe related to this?

Any ideas?
TIA,
Steve

Hi
Does 7c1264a address this?
Cheers

Steve,

Yesterday I looked at that first crash you referenced, and seemed to make it go away with the change you pointed to. Honestly, I didn't feel I totally understood what was the root issue. I don't think there's an issue with the stretching itself so much as the memory it's being passed. Can you please test with the patch you pointed to and see if it clears up your issue? It's in the latest code, so a git pull would get it (or you could just remove those 4 lines from fitsview.cpp and recompile).

Thanks.
