This happens all the time.

I don't see why we close bug here?

More info: it seems to crash on boxes that have several keys etc, not so much on clean installs that so far do not have opnepgp keys or just 1 or 2.

Another crash:
Application: KGpg (kgpg), signal: Segmentation fault
The current source language is "auto; currently c".
