Crash while downloading dives

[Henrik Brautaset Aronsen]

It's been awhile since I tried downloading dives with Subsurface.  But I 
just tried it again, and the download dialogue and progress bar looks 
really smooth now! Kudos!

Just one little thing, though:  Subsurface crashed while downloading.  I 
wasn't paying attention, but I think it must have been while as it 
finished downloading.  Here's the stacktrace:
