This script calls invoke-rc.d to run an init script but then, if the init script fails, exits successfully (using || exit 0). If the init script fails, the maintainer script should probably fail.
The most likely cause of this problem is that the package was built with a debhelper version suffering from Bug#337664 that inserted incorrect invoke-rc.d code in the generated maintainer script. The package needs to be reuploaded (could be bin-NMUd, no source changes needed).
