I don't know why it's happen, the only thing that I've done is to add a new HD on my server with amuled and restarted, on the first boot ubuntu 11.10 cant recognize the partition with Temp and Incoming files and when opened amulegui on local hosts download tab is empty but when mounting that partition the files are there.
after another restart the SO correctly mount the temp and icoming partition but I get always empty download tab...
