kstars hang when FITS viewer histogram displayed - by: adonf

I did not understand the reasons for the crash of kstars only during my catches of flats, but not with lights.
I finally found the cause.

I left the histogram window displayed to see the effect of setting my flat box. Systematically kstars planted after 3 or 4 photos.
All I need to do is close the histogram window with each test, and then I can chain a series of flats without any problem.
