Uncaught TypeError: Cannot call method 'slice' of undefined

[jbeilicke]

I just updated my trac installation to jQuery 1.7.1 and DynamicFieldsPlugin r11034 (0.11 branch). When loading a ticket, I am getting the mentioned error in layout.js:175. In the page there are some empty table headers without ids that seem to trigger the error.

This patch seems to work:

 };
