Dino freezes X on Linux when importing an OpenPGP key

[ar1ja]

Hello,

When importing an OpenPGP key into Dino by means of UI, it freezes the whole system until the window manager is killed. I believe this may be a problem where dino may call to gpg or alike to decrypt a private key and that somehow causes it to hang the input(?) X thread, making the UI of the system unusable.

Dino version 0.5.0.
