Empty Changeset causes null pointer

[Craig Hewetson]

The changeset some how is null and then a null pointer gets thrown:

If I can get the maven build going for this project I could fix this bug. and even contribute features.

Hi Craig,

Thanks reporting this,

This might be related to not handling an error when the change set is parsed.

What's the issue with the maven build?

Did you configured maven wfollowing the instuctions at
http://wiki.hudson-ci.org/display/HUDSON/Plugin+tutorial (Setting up
the environment section)

Hi Guillermo

I must have done something wrong previously but now all is well. I had to
update the bzr-hudson pom.xml file to make use of bzr-java-lib 0.5.1 and not
0.5.0. I have summitted the fix on:
