Problem with file-history session save

[Elaine Meng]

save ~/Desktop/tethers.cxs
Session file format is not finalized, and thus might not be restorable in other versions of ChimeraX.

I opened the attached cxc file and then rotated/translated/zoomed by hand and then tried to save session from the command line. Also attached session, seems OK upon restore.

Fixed.

Oops. File history changes to remember open options broke remembering file. The saved session file is correct. The error occurs only after the save completes when it tries to add the new session file to the history.
