Null Pointer Exception: build-timeout-plugin

Using version 1.12 of the plugin on Jenkins version 1.530

When I choose "Abort the build if stuck," there are no strategies available to choose from:

When I then try to run a build, I get a null pointer exception:

12:34:27 FATAL: null

This affects only new jobs created after upgrading; jobs configured with the previous version of the plugin continue to work as expected.

Downgrading to the previous version (1.11) and reconfiguring the job resolves the issue.
