Fix your shitty N900 yourself.

Guess what? Probably many many users are using sygic and it isn´t crashing on them. So to make your statement believable please fill bug report and most importantly make guide to ALL how to reproduce the issue so people can confirm that it is really issue and not just your device that has possibly HW deficit or user error (tweaking system files, overclocking, installing stuff from devel &testing etc. that usual that might brake things up).
