Looks like an exception in AbstractRepositorySettingsPage...

java.lang.NullPointerException
at org.eclipse.mylyn.tasks.ui.wizards.AbstractRepositorySettingsPage.<init>(AbstractRepositorySettingsPage.java:212)

You would need to fix this first (if you can modify the source) or create your own concrete intermediate class that addresses that issue.
