On regular basis I get a crash in Lightroom when load a GPS track in the map module. This usually happen when I load more than one per session. When this happens restarting Lightroom and loading the GPS track again works.
The GPS track in in .gpx, generated by HoudahGPS
This problem exists since the initial beta of Lightroom 4. Still happen in the 4.3RC. This is on Mac. I have systematically sent the crash report to Adobe (check with my email address if you have access to them)
The only reason I report it here is because I was told the crash reporting is not useful.
