"set:Menu:None" means that you just went to the map view. BTW, does the freezes or reboots always occur while looking at/manipulating the map or also while in menu ? BTW, were you in fullscreen when the reboot happened ?

This message occurs after batch loading of tracklogs is completed. Batch loading is mostly used by the track drawing code, to quickly load all tracks that need to be drawn. Maybe you can try if modRana reboots when there are no tracks with enabled drawing ?

BTW, I find it still pretty weird that just a simple application can freeze, let alone reboot the whole device...

I have tried some little stress testing (PR1.3, vanilla):

• started a 1,7 K tile download
• did a "draw all on tracklogs", including one 2000 km long one
• let it sit a while

Nothing strange happened, the device only got slightly warm. I have also used it to play music the whole time, without a single hiccup (they really did a great job at this in PR1.3!).
I guess I'll have to do more testing then.

(This does not mean that I have never seen modRana freeze the device, but its quite a while since this happened to me last time. On the other hand, my N900 recently restarted while the Nokia pano ap was processing a new panorama.)
