Description Bernhard Beschow 2011-09-13 11:53:38 UTC 
Version:           unspecified
OS:                Linux

When the "GPS Position Simulation (File Reader)" is selected, Marble crashes immediately, regardless of whether a route is loaded or not.

Reproducible: Always

Steps to Reproduce:
1. Optional: create a route
2. Select "GPS Position Simulation (File Reader)" in the "Current Location" tab.

Actual Results:  
Marble crashes immediately.

Expected Results:  
Perform route simulation (or whatever).
