[Marble-devel] The Japan Conspiracy (crash)

[Frederik Schwarzer]

Hi,

(if you have further questions please CC me)

I managed to crash marble twice. First I realized that I forgot to install 
gdb. ;) Then I got a backtrace.
The interesting thing is that it crashed both times when I tried to find Japan 
in a high zoom state and was a bit south of Taiwan. I dragges the world 
around with the mouse and *bang* marble crashed.

Here's the backtrace:
Using host libthread_db library "/lib/i686/cmov/libthread_db.so.1".
