Maybe someone has an idea:
74 LyXView::LyXView(int id)
75 : work_area_(0),
76 toolbars_(new Toolbars(*this)),
77 autosave_timeout_(new Timeout(5000)),
78 dialogs_(new Dialogs(*this)),
79 controlcommand_(new ControlCommandBuffer(*this)), id_(id)
80 {
when crashing it goes from line 79 to the ctor of Dialogs and I
assume that the crash happens there.
The last patch there is
http://www.lyx.org/trac/changeset/18684
rc1 was released at May 31, the patch is from May 6. The patch adds a connect
and you have a crash in the boost/signals. Bingo.
Could you check if this line is responsible to your crash by commenting it out?
