Thanks Vincent, I no longer get a crash. I still have the following issues (let me know if I should open up tickets): - When selecting all and copying UserGuide.lyx, I get the dialogs mentioned before. - When selecting all and copying Addional.lyx, I get the following message: "LyX does not know how to include non-LyX files when generating HTML output. Offending file: SpecialParagraphShape.tex" - When selecting all and copying EmbeddedObjects.lyx, I get the following errors: File '/tmp/lyx_tmpdir.n11551/DummyTextDocument.txt' is not readable! support/FileName.cpp (732): File '/tmp/lyx_tmpdir.n11551/DummyTextDocument.txt' is not readable! support/FileName.cpp (732): File '/tmp/lyx_tmpdir.n11551/EmbeddedObjects.lyx' is not readable!
