When I try to drag item to other folder lis.to halt. It happens only
at Linux.

Steps:
1. I create a task in Inbox
2. I press mouse's button and drag a task to other folder, icon is
"unavailable" (/).
3. I release mouse's button.
4. Desktop is unavailable: I can't switch application, mouse not work,
keyboard not work.
5. I switch to console and kill lis.to.
6. Desktop is available.
