An alternative would be to use KeePass, works very well on linux. It's one file, and that's it.
I use it with the great PassIFox (https://addons.mozilla.org/en-US/firefox/addon/passifox/) to get a nice "Fill user/password" in the contextual menu.
I also use it on my Android phone with Keepass2Android: https://keepass2android.codeplex.com/
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).
You can see the commit activity for KeePassX, which would make it more obvious if a bug or malicious snippet might get inserted into it.
