Start downloading a file of size 200M, then start another of 10M -  the progress
indicator in the window bar indicates the mean of the two downloads - so if the
10M file is (say) 50% complete and the 200M file is 10% complete it will show "2
files 30% complete" - rather than ((10*200+50*10)/(200+10))% complete.

Reproducible: Always
Steps to Reproduce:
1. Start downloading a file of size 200M, then start another of 10M
2.
3.

Actual Results:  
the progress indicator in the window bar indicates the mean (arithmetical
average) progress of the two downloads

Expected Results:  
the progress indicator in the window bar should indicate the median (weighted
average) of the two downloads
