I think I see what's going on. The crash only happens if you hit backspace when the cursor is in front of an *opened* collapsable (a closed collapsable gets deleted, as it should be). Now LyXText::Delete basically just moves the cursor to the right and calls LyXText::backspace. That is, if the collapsable is opened, the cursor gets moved *inside* the collapsable. That triggers BOOST_ASSERT(this == cur.text()) in LyXText::backspace. I guess the collapsable should be closed before cursorRight or the cursor should just jump across the inset. Over to the A*-Team. Happy easter, Jürgen.
