I create a Custom Group, right click and choosed Group Policy. I change the Maximun share ratio to 1.05.

If I then right click on a torrent and choose my Custom Group under Add to Group ktorrent hangs with 100% CPU time. I let it alone for 10 minutes and it stills hangs and uses 100% CPU time.

I tried this on a 6GB and 32MB but the result was the same.

I have tried reproducing this, but failed.

Either way this looks like an infinite loop somewhere, I will check out all the code involved.

It is fixed, it will work if you select the first group in the menu, but any group after that would cause the bug.
