[Test Case] Unfortunately it is not possible to reproduce this bug at will. Apparently is is caused by an uninitialized pointer dereference that only occurs in a timing-dependent manner. Running a full autopilot test suite against the Unity desktop shell reveals no new regressions. [Regression Potential] The code change effectively adds a test for a null pointer. It is possible that this might introduce a regression in drag-and-drop functionality that previously relied on undefined behaviour to work when it didn't crash. [Other Info] Fix was released with Ubuntu 14.10 and no new regressions have been reported.
