When you make a purchase using the Magnatunes integrated store, Amarok 
issues the payment instruction multiple times, resulting in overcharging.

While Magnatunes are very good at picking up on this (it seems it's an 
upstream bug that's happening to a number of people) and reversing the 
charge, it strikes me that a bug that costs users *actual money* 
deserves at the very least a "serious" tag. (Credit card fees and 
currency exchange rates means you don't get the full amount back if 
you're not paying in US dollars.)

Reproducing the problem: go to the Magnatunes integrated store, 
right-click an album title and select "purchase". Enter your credit card 
details and click "purchase".

Expected behaviour: get charged the chosen amount, once.

Observed behaviour: get a single confirmation that the transaction has 
been a success, with links to download the track. But then emails come 
through indicating that the transaction has in fact been processed more 
than once - I'm currently looking at three separate confirmation emails 
for a single purchase, with three separate charges to my card.
