Lag when selecting an item or pressing enter in the universal search of the Dash

[ftkw]

In Ubuntu 13.10, when entering something in the default Dash and pressing Enter, there's a delay of about 2 seconds until the application is started. In these 2 seconds, the little spinning wheel to the left of the entry field is spinning.

This delay is lower (~1 second) when using the applications lens (Super+A) and pressing Enter to open the first result that is shown.

The delay can only be observed when additional/online results are still being searched.

This lag did not happen in 13.04, 12.10 or 12.04 for me.
