Opening the Tomb aborted as the app doesn't ask for password.

[Dudeson1337]

Today I bumped into a problem that doesn't seem to be covered a lot, as I tried to google for a solution and didn't manage to find one. I might be overlooking something here, but here's what I get when I try opening the tomb:

tomb  .  A password is required to use key /(...).tomb.key
pinentry-gnome3: error while loading shared libraries: libgcr-base-3.so.1: cannot open shared object file: No such file or directory
tomb [W] Empty password
tomb [W] User aborted password dialog.
tomb [E] No valid password supplied.

I don't get to enter a password, it just escapes the program after printing this. Previously everything worked fine, but after I reinstalled an OS, this is what I get.

I'd be thankful for any advise.
