Comment 4 for bug 1495302

I have done debugging and found the exact place where postinstallation script stops:

My $services at this point: "openvpn ntp apache2 ":\
>
> if [ -n "$services" ]; then
> db_input critical libraries/restart-without-asking || true
> db_go || true

OK until here, script breaks now with this line:
> db_get libraries/restart-without-asking
>
> if [ "x$RET" != xtrue ]; then

I don't know how to fix it, but I can help testing solutions.
