I have the same problem in both 0.38.0 and 0.38.1. Although mine lasts longer than 2 minutes. It lands up using about 1.8 gig of ram before showing the error dialog although it carrys on downloading for a while. Later on it just shows it cant connect to servers although i cant try anything else as the dialog is modal and wont close. I have stuff in my queue , my auto import is active but the folder is empty. Will try deleting the queue folder once the stuff i have is done to troubleshoot.
