Thanks for pointing this out, it turns out that when seeking I was  
accidentally truncating to seconds when converting the double to the  
internal time representation (uint64 nanoseconds). Remember kids, the cast  
operator takes precedence over multiplication! Anyway, this is now fixed  
and will be in a future Opera release.
