Hi again,
while trying to make my patches explode, I saw yet another old
annoyance: LyX'
second, third, etc. (forked) thread crashes. Debugging by attaching to
child's
threads (where you never know which one crashes, others only freeze)
was always
to complicated ... And main thread (with the docs) is safely protected
by the
kernel; so it's only an annoyance to see all those render childs sisegv
one
after the other.
For the first time I got a bit meaningful core dump (though I doubt it
can help
too much):

[Here's my main interest:
I made NormalizePath() a static function of src/lyx_main.C, as it's
only used
there. Am I right, that signal handler call (SIGSEGV in some forked
child)
happened before and my patch can't be the reason for the crash?
