Andre', JMarc,LFUN_ALL_INSETS_TOGGLE calls LFUN_INSET_TOGGLE for every inset in the doc. LFUN_INSET_TOGGLE (Ctrl-i) works fine when used directly within a math inset (by fine I mean it does not crash, I am sure I like the behaviour). It seems that the problem lies in the passed temporary cursor in LFUN_ALL_INSETS_TOGGLE.
