Plugin crashes when pull request has merge conflict

[iradul]

Our private github repo is triggering Strider every time someone creates pull request.
If pull request can be successfully merged everything works well but if there is a merge conflict strider-git module crashes and I'm ending up with forever pending status ( strider-github-status ):

This is where job gets stuck :

  strider-git:worker Git Version:1.8 +360ms
  strider-git gitane command done git clone --recursive git@github.com:*******.git . --branch master; exit code 0; duration 1223 +1s
  strider-git Gitane error: +259ms undefined
  strider-git gitane command done git fetch origin refs/pull/14/merge; exit code 128; duration 258 +1ms

Exception is coming from git fetch origin refs/pull/14/merge which can't be resolved since there is a merge conflict. Everything goes south on prepare stage:

Error: Fetch refs/pull/14/merge failed with code 500

From your point of view, should it fail the build?

[iradul]

Yes absolutely, that would be much better indication that something is wrong.
For example Jenkins has ability to handle test/build errors with special kind of status message (failure or unstable).
