Crash and reboot after using Running-app

Since a week or so the S60 crashes and reboots with the Running-app. The app works fine but when I end my running round and want to view the details, the watch crashes and reboots and the results of the latest activity are lost. Happened to me last week and today again. The first time I had to restore all the watch faces and lost the latest activity, the second time I lost some of the watch face settings and the results of the running round.

Looks like a software issue since the last update because I didn't have these problems before. 

@Garmin: when will this be fixed?
