[Tom Goddard]

This crash is in the Python Image Library, not in ChimeraX code. I've seen it reported before always in ChimeraX 1.3 and Linux 3.10. It appears to be a problem with the Python Image Library in this Linux version, not something we can fix. Newer ChimeraX versions do not support CentOS 7 because the Qt window toolkit dropped support for it. So even if it was a problem in the ChimeraX code we cannot provide a fixed ChimeraX on CentOS 7.

[Tom Goddard]

Does it crash on every image save? For instance if you open no data and just type "save test.png" does it crash? What if you open your data and use "save test.png" without the "supersample 3" option? What if you save as jpg "save test.jpg"? If none of these work, you could save a ChimeraX session (save mysession.cxs) and copy it to a machine where ChimeraX works, load the session and save the image.
