Javscript error on rsitempicker.aspx post SP2

Hello,

I applied SP2 to our DEV and TEST farms during the summer and instructed our users to test it before I applied it on the production farm. Some did but apparently not the BI people because the morning after I applied to SP2 I get a mail that the popup used to chose Data Source of SQL Reporting Services Reports (rsitempicker.aspx) results in a Javascript error.

And it's in all 3 environments now and no going back. Simpe work-around though, just click "No" on the Javascript error and then chose a datasource using arrowkeys and Ok. Or use Chrome or Firefox because it works perfectly in those browsers, but not in MSIE 8, 9 and 10 which are the ones we're using.

To try to reproduce the error, just go into a BI library with a SQL Reporting Services Report and use the dropdown and select Manage Data Source, then click on the Data Source and then click the "..." button to browse for a source and try to left-click on anyone and it'll display the error.

Or is it just our farm?
