James_Littler : Yes, my camera app works (and BlessN900, and FCam...)
How to contact the authors, on OVI store, there is no link or information...

ME2g : My /home/user/MyDocs/Panorama is :
permissions : 777
ownership : user.root

I can write on it.

I don't have quickpanorama (pro or not) installed, so I don't have the symlink you talk about. But I've the following :
/usr/bin/panorama -> /opt/maemo/usr/bin/panorama
The target file is :
permissions : 755
ownership : root.root

I really think the problem is not permissions related, but "USB storage" detection related.
