Ok, the problem is that the accessibility is not enabled, as the log says:

** (<unknown>:6511): DEBUG: Unity accessibility initialization

** (<unknown>:6511): WARNING **: Accessibility: invalid module path (NULL)

But we are trying to add that window to the accessibility system, not initialized:

** (<unknown>:6511): CRITICAL **: void unity_root_accessible_add_window(UnityRootAccessible*, nux::BaseWindow*): assertion `UNITY_IS_ROOT_ACCESSIBLE (self)' failed
Segmentation fault

Although this manual adding is temporal, I will add a check in order to avoid this crash meanwhile. I will take this bug.

After checking this a little, just to comment that this error message shouldn't be the cause of the segmentation fault.

I was able to reproduce it, but unity works fine (warning there, but works fine).

Although I still plan to avoid that warnings, take into account that likely it will not fix the segmentation fault.

The branch that I have just linked solves that warning

Anyway, as I said, I really doubt that this Segmentation Fault caused by this reason.
