Error when navigating away from Dashboard

I have created several Dashboards in CRM2011 (on premise) for my client.

They all work fine, but when navigating away from the Dashboard to for example Quote or Order entity (by clicking in the navigation pane in the left) an error is displayed almost always (Its the generic error that allows you to send error report to Microsoft).

I have pasted the error message below, but it seems to me that it occures in a script that is not necessarily 'man made'.

This occurs for anyone using the dashboard, so its not related to me/my business unit.

Has anyone else experienced this, and how do i fix this?
