Hi Guys, I was working on a rather large document today when lyx started crashing whenever I opened it.
I opened a bunch of backups that all seemed to work when suddenly they started crashing too. That caught me by surprise, so I started poking around the subversion code. The offender was a failed assertion on line 245 of src/inset/InsetCollapsable.cpp : BOOST_ASSERT(status() != Collapsed); I guessed that it must be something to do with insets being collapsed by default when the file is first opened. So I tried renaming the file and opening it under the new name, then saving that to the old name. That worked, so I am guessing that the cursor position (stored in the session file) is used without ensuring that the inset isn't collapsed. Hope this helps one of you wonder-hackers :)
