Waiting animation cursor persists long after file opened via double click

[Teo]

Steps to reproduce:
- open a folder in Nautilus
- double click on a text file that will open by default in GEdit
=> the cursor starts showing a waiting animation (rotating dots in a circle)

Expected behavior
=> As soon as the file is opened in Gedit, the cursor waiting animation should stop, wherever you move the cursor

Observed behavior:
=> while you keep the cursor within Gedit, it is an arrow as expected, but as soon as it move it outside gedit and/or click again on the Nautilus window, the cursor keeps showing the waiting animation for several seconds, about 10 seconds no matter what you do. After that time, cursor goes back to normal.

This is a regression that has appeared in Ubuntu 13.04. Worked fine in 12.10

Now I realize, the bug may be in Gedit rather than Nautilus. This doesn't happen with files opened by default by other programs.

However, if the behavior of the cursor outside the called application (i.e. Gedit) depends on the called application, then something is badly wrong (either in implementation or design) in either the calling application (i.e. Nautilus) or the system (i.e. Unity).
