Ok, I applied the patch by hand.
Then I compiled and started amule. As usual it starts and after the initial checks starts to scan the shared directories and appears aMule window on the screen, at the same time the download window appears on the screen but until now both windows are blank and stay blank until the end of the scan.
As soon as the scan ends the two windows are filled, but the download window is just like the attached photo and stay there undefinitely.
I gave a Ctrl+C and attached I report all bt and logfile. I hope they are useful.
