I have the same problem when using gutsy in persistent mode from a usb stick. I know persistence has been broken, but I have been thinking this failure of gnome network manager to maintain the key might be a different issue because some of the persistent functionality in gutsy has actually worked for me.
Note, I believe some people may have experienced this same network manager issue in the patched feisty iso that was prepared in which persistence worked. Don't know if that was the same problem as this one (particularly if normal (non live-cd) feisty installations didn't experience this problem. But, I wanted to mention that in case it is possible this issue was introduced by changes back in feisty (don't know if that might help in the trouble shooting).
Alexander, it might be intersting to see if your problem persists with the feisty version of gnome network manager and, if it does, with the edgy version of network manager. You could revert to each of these by creating a preferences file in your /etc/apt directory and pinning gnome network manager at the feisty and edgy versions of the gnome network manager, respectively. (Don't know if they will be compatible, but you might try if you have time. I might try that as well).
