Hi,

I've upgraded hudson from 1.179 and task 1.6 plugin to hudson 1.94 and tasks 2.1.

Now the build with the tasks enabled doesn't works.
When I enter the Job-Page, the styles on the page are broken, and the task-graph
shows the broken image.

In the build-console, I get the following error after the build completes
successfully, so the build breaks:
