Several of out build jobs using git are broken since some of the last version of the git plugin. They are crashing already in the main job triggering the individual builds with the following exception:

Finished: FAILURE

All of the crashing jobs are matrix jobs using git and merging from a separate branch. Other jobs with git without merging are not affected by this.

We are currently using version 1.3.0 of the git plugin and this version is affected by this bug.
