ok, lets start...

• import some waypoints
• use the find function to find one by name
  it gets displayed in the properties dock
• on the search result, use "center map" from the context menu
→ map centers on something like 0,0 (but the waypoint is in berlin)
• use + to zoom in
→ segmentation fault

surprisingly, "center and zoom map" from the context menu does not crash
(but puts me at 0,0 at 200m scale).
using a bookmark to get back home then crashes it.

the stack trace seems to be the same for both crashes:

Program received signal SIGSEGV, Segmentation fault.

not a crash: "history" and "referenced by ..." in the info dock don't
work since the 0.6 API, but you're already adressing this for 0.13.2?
