Comment 9 for bug 854615

Further analysis shows that the bug cannot be reproduced on a similar HW (Jay has the same GPU available in his lab).

This hypothesis is further confirmed by the existence of this other bug https://bugs.launchpad.net/dee/+bug/840758 related to asynchronous results causing crashes in Unity.

Combining the 2 elements, it looks like Gord's fix could apply to your particular problem: https://code.launchpad.net/~gordallott/unity/fix-music-lens-causing-crashers/+merge/76761

Please look for the next point release upload on Monday.
