This looks like the Mac OS X timer bug again. The libdivecomputer SHA1 
confirms that this is indeed a version without the timer fix.

@Dirk: It looks like v4.8.0 got build against an old libdivecomputer 
version. According to tags in git, it should be build against 
02560a7e7fe82919d584d3edbf3876f90382052c, which includes the fix. But 
the logs in the bugreports indicate otherwise.
