Error in postinstall script

[Yann Rouillard]

I get the following error when I try to install preload:
/var/lib/dpkg/info/preload.postinst: line 25: [: =: unary operator expected

full output is:
sudo apt-get install preload

The error was caused by missing quotes around a variable:

case "$1" in
    configure)

    # This was supposed to go to /var/lib/preload/
    # (rm this after etch=stable?)
    if [ $2 = '0.2-1' ] ; then
        rm /var/cache/preload.state || true
    fi
    ;;

variable $2 is empty when the package is installed for the first time, hence the error message.

Thanks for the patch! =) Please set to "Fix Committed" only if the updated package has been uploaded into the archive, to which end I'm now working on.
