Version: 2.18.0

What were you doing when the application crashed?
Chinese 一天以前我打开了立方体上工作区， 刚才我正在安装互联网上的软件包。我将Pidgin拖动到1区右边，立方体转动到二区，我发现不对劲，以回到一区，再回到二区，就这样了。
English  A day ago, I turn on the desktop effect of desktop on the cubic. I have been installing softwares via application->Add/Remove since yesterday throughtout the whole night till this morning.  When I drag Pidgin to the right side of desktop 1 it turns to desktop 2 but I find that it is not right, then I trun back to desktop zone 1 then back again. Then the bug report appears.
