Browser Interface broken in IE8, IE9, IE10

[andi-blafasl]

Inside a Library you cannot create a New Folder, New File, or Sharing.
If you click the buttons on top, the IE errors with

SCRIPT438: Das Objekt unterstützt die Eigenschaft oder Methode "removeExpression" nicht
Datei: main.277def0b4696.js, Zeile: 205, Spalte: 274033

Excuse the German error message, but I think the Problem should be clear.
You can also reproduce the Problem in IE11 when setting the Emulation Dokumentmode to IE10

I found a simmilar bug here: ericmmartin/simplemodal#58
Maybe the solution there can be used in seafile as well.
