Confusing popup - File Transfer in progress

I noticed a couple of times that when I try to close a session a popup appears telling me a file transfer is in progress. First, there was no file transfer started during this session, opening the transfer box, it is empty. Second the buttons are extremely confusing.  In Dutch you have to choose between `doorgaan` (continue) or `annuleer` (cancel). Naturally you choose continue, as you want to close the session, but it is the other wat around, to close you need to select cancel.

Either this buttons are mislabeled or  the text should be different.
