the -w flag was forgotten when using the 2to3 tool in the build.
will upload a fix to debian and sync shortly.

[Michael Vogt (mvo)]

Thanks.
This is now fixed in debian and we just need to sync 6.2.0-6 from incoming.debian.org.

[Michael Vogt (mvo)]

The sync is not super high urgency as the version in natty has a fix for this as well.

[Michael Vogt (mvo)]

(but the -n addition is worth the sync)
