are you using ccpem jhbuild or using the build-it script? Or something else?

Oh dear - that look like I left behind some debugging :-(

Yes. First person to mention it (congratulations?). The difference
between the eyes is now a shear, not a rotation. This means that you
don't get part of the structure and map that is in one eye but not the
other - which should improve (as in reduce) eye-strain. There are still
weird visual effects if you letterbox the window.

This doesn't ring any bells. Can you use gdb on the core file?

Yes, this looks like the sort of thing to expect if one is using the
wrong/new/modern/supported version of guile-gtk - it looks like
coot-main-menubar isn't returning a value that coot-menubar-menu can
deal with - I will need to look at the glue between guile and c/c++.
If needed, you can compile coot without guile and it works pretty good.
