maven-debian-helper and pom.xml patching problem

[Eugene Zhukov <jevgeni.zh@gmail.com>]

Hello,
I am trying to fix packaging of [1]
First debuild run works perfectly, after that only every second one succeeds.
It happens because some automatic pom.xml patching/unpatching fails.
After playing with quilt commands debuild starts to run successfully
every time. But once you unpatch pom.xml, delete .pc folder and start
from scratch- you are back to square one.
Any idea how to fix this once and for all?
