I'm using 0.5.3 (love the split downloads from multiple hosts.. Muhahahah), and it seems that if Qtella is up for a long time (I left it up overnight), everything seems to work fine except all attempts at downloads immediately tag the host as "Error", and the download subsequently fails.

Quitting and restarting Qtella clears it up.

Also, Qtella 0.5.3 doesn't seem to save the hostlist.. if it does, it doesn't seem to be using it when Qtella is restarted.

I do get some random crashes, but they have been infrequent enough that I haven't noticed a pattern...
