Version ?

In the Subject thats the svn revision. ie: r639769

Oops, need to turn on brain

This happens immediatly or does it run for a couple of seconds ?

It runs for a few seconds in that it has to scan my rather large list of active and inactive torrents (64 total). It takes ktorrent about 10 seconds or so to finish scanning and loading the torrents.

I think it started because I ran out of diskspace on the drive that ktorrent downloads to as well as where I have it set to store the ktorrent metadata. I have since made some room, so it should be ok.

Doesn't seem to be disk IO related. It happens when we are checking if all peers of a chunk download are choked. This shouldn't happen.
