1. Don't manually patch something
2. To me that looks like a bug that got fixed by now probably more than
a year ago, IIRC. Back then the bug was that this "debug output"
including '.' was printend on stdout, and then got mixed into other
commands.

So my best guess is you are using very very outdated versions.

dpkg -l | grep drbd # would help
