I have LyX-1.6svn set to open files from the last session, and currently it is set to open 3 files. There are a number of bugs with the way this works, as I have reported in the past. One bug is that although I last quit LyX with these files open in separate windows, on relaunch, LyX opens them in one window with tabs. (On Mac this is a problem because in 1.6 <opt><tab> does not work to switch among these tabs; this is a regression from 1.5.) Another bug is that LyX now opens them with the source view and outline view visible, which it should not (given that they were not visible when LyX was last quit.) I mention these problems because it seems they may be relevant to the current crash I'm getting.
Currently, with these 3 files set to open in the sessions file, LyX crashes on launch soon after displaying the document window. If I delete the sessions file, LyX launches with no problem, and I am able to open these 3 files individually. When I quit (with these files open) and relaunch, I again get the crash. Here's the backtrace. Bennett Program received signal EXC_BAD_ACCESS, Could not access memory.
