Same here, using the official one with Mono. It's a bit buggy, but still works properly most of the time. Do you use keepassx on Linux, and if so, does it work well?

KeePass is the program for linux I've found that fills in your details in the browser for you (short of LastPass, which I don't trust).

I don't use KeePassX. While it run/looks better on Linux (which is my main system), it doesn't support plugins (so no PassIFox, I could live without it but I'm lazy) and the interface is less mature.
