Indeed this is a related bug. The menu expansion crashes now in
MenuDefinition::expandSpellingSuggestions().
I tried to add an early return there if we are in math mode. If I do so I can
see the real cause for the problem: the right button opens the wrong menu. It
should be the math context menu and in fact it is the normal text menu. But
only the first time - if the crash is avoided every following right click opens
the math menu. So, there is something wrong with the menu binding. I don't know
enough about that machinery... but the early return patch only hides the root
cause I think.
Please, can any menu expert have a look?
