Crash on zooming/setting position in (K)ubuntu 14.04

[martin tlustos]

When trying to set a location, or zooming the map, X crashes. Xorg.log output:

This happens both with gtk_drawer and internal gui. (navit.xml attached, but I tried both the gtk and the internal ui.

I was facing a similar issue on Gentoo some times ago. This seems to be a bug in the intel graphic driver. On my own device, it was crashing while rendering coastlines at specific zoom levels, and the stack trace looked like yours. I have reinstalled the device a 3-4 months ago and haven't seen this issue since. Please make sure that you run an up to date version of the intel driver and the X server. You might want to try to switch to Cairo too as it will also bring some rendering improvements.
