Custom properties get overwritten by conversion generator

[AshPowell]

Hi,

I'm trying to set image dimensions as a custom property by setting a handler for the MediaHasBeenAdded event.

The media model gets updated but then it seems to be overwritten by adjustments made from conversions, but if I listen and act upon the ConversionHasBeenCompleted event - it doesn't guarantee that im not going to hit the same type of race condition if I have multiple conversions.

Any ideas how I can get around this without calculating the image dimensions at a later date?

Thanks
