Can you run "sh -e -x dpkg.preinst upgrade 1.15.2" with the attached script
and send me the output? Also send me the content of the last alternatives
file read by the script (will be visible in the log).
I expect one of the files to be broken and have an inconsistent number
of lines... which could lead to a read call failing. I'll fix that
shortly.

One of those very short files could be at fault maybe.
