LibreOffice crashes kernel while trying to open 500+ new windows.

[Robert Pearson]

I am trying to combine 500+ .tiff files into a single .pdf file. I read that LibreOffice could do this. I started LibreOffice and selected the .tiff files. LibreOffice immediately tried to open 500+ new windows. I tried to close LibreOffice but got an error window warning that LibreOffice is not responding. When I selected kill any way, nothing happened. Eventually the entire screen went black - the kernel had crashed. Had to reboot my machine.

Still need to convert many tiff files to a single pdf file (preferably without using ghostscript like tiff2pdf).
