Ogre3D based game crashes on exit

[Saulius Krasuckas]

The game [1] crashes when I select DX7 engine at its initial screen, go
the gameplay and then simply exit.  I have entered a new bug report to
provide more details [2] on this issue.

My attention was caught by the ending part of the output [3] (quite large,
about 400kB in size):

Any ideas on how to investigate further on this crash?
