Martin (and Mathieu), it would be helpful if you could include the package version in question in your "accepted into ... -proposed" boiler-plate.
Anyway, I think I was never able to systematically reproduce this bug and did not see it often, so I will have difficulties to confirm any fix. Using 1:3.4.1-0ubuntu1 now (which I believe does not have your fix) but I can not make it crash by clicking around in the Network preferences. If the crash is dependent on having a hidden ESSID in the neighbourhood it is even more difficult to test it conclusively.
