I don't *have* a binary that executes. I believe that the same binary
that crashes was the same that previously worked. As I stated, I
rebuilt the LyX port, and the core Qt libraries without effect (I
build ports using portmaster). Since them, I've tried to install the
binary using "pkg install lyx", with the same result.
% ldd -a /usr/local/bin/lyx | grep Qt
libQtGui.so.4 => /usr/local/lib/qt4/libQtGui.so.4 (0x28e7f000)
libQtCore.so.4 => /usr/local/lib/qt4/libQtCore.so.4 (0x29a6b000)
/usr/local/lib/qt4/libQtGui.so.4:
libQtCore.so.4 => /usr/local/lib/qt4/libQtCore.so.4 (0x29a6b000)
/usr/local/lib/qt4/libQtCore.so.4:

I normally build ports using portmaster, but as I said, trying to
directly install the binary using pkg install didn't help.

Perhaps, but I don't know how to track it down.
The installed versions of libQtCore and libQtGui seem to be 4.8.7,
which I suppose corresponds to the version 0x40807 in the error
message. I don't know how to identify how version 4.8.6 is coming
into the picture.
