Elevating importance and targeting to beta2 because a duplicate bug has such status.

From reading the backtraces I thought it may be related to the minimize animation (which was applied on any window type up to now), although I could be wrong as the animation name is nowhere directly given in the trace and the line numbers apparently changed since it was generated.
So maybe, just maybe, it could work now, as we no longer animate non-normal window minimizing.
