There seems to be a problem with the "Actions" section.
Quite often when I'm using that section, I can't go to any other section or the dashboard.
The links simply don't work. I'm redirected to the page I was on.
Last time it happened, I was on the "Page titles" page, in week view, but I remembered it happening on other pages.
The page names look normal. They using the following special characters:
accentuated characters () are also used.
Just wanted to add that reloading the page solves it and that I'm using a Webkit based browser.
I believe this is fixed in trunk.
