Project is stuck in the "Build in Progress" state if the associated exception has more than 8192 chars

We have added unit tests to one of our project and some of them are crashing from time to time due to a race condition with the database connections.

Since then, the project is always in the "Build In progress" state even if the build is actually terminated in the log (Build failure because one test failed). The project never leaves this state, if we consult the builds summary we have a couple of builds in the Build In progress state (?!)

See screenshot.
