Hi all,
in an attempt to extend my debugging capabilities to catch the crash bugs on
Mac OS X I enabled the memory management debugging utilities.
See

The first hit is Qt related and at this point the game is over.
The offending code of LyX's BackgroundWidget constructor looks completely valid.
/// The text to be written on top of the pixmap
QString const text = lyx_version ?
qt_("version ") + lyx_version : qt_("unknown version");
What if you replace the string by a static one?
Can you display this string on lyxerr? Can you explicitely translate
lyx_version to a QString?
One thing to try for this kind of bugs is valgrind.
