I am having problems with setting up the right appliction for opening the url link inside mail.
After the installation when i clicked on the URL link i was asked to chose the application (although under system settings default applications i had firefox).
I did chose the application but nothing happened, the application just didn't start. And after that I wasn't asked any more to chose the application prefernce for the url links. I tried to change the application preference on the cog-wheel in the bottom right corner but the preferences are empty, there is no contenet there. So now I can't open any url from the mail and i can't chose the application to open it. Is there anyway to solve this.

My environment:
Ubuntu 11.10 64 bit
Zimbra 7.1.4
