File stuck in trash folder.

Hello,

Lately, it seems that there is a file stuck in the trash folder.

When I press "empty trash", it deletes all folders that are in there, except that one. No errors or pop-ups of any kind occur, it's like the system actually thinks that it deleted all files that are in there. However, the one file remains stuck in the trash.

The file I'm talking about is something I downloaded using "vuze", a bittorent program.

What can I do next?

Thanks in advance!
