*** Bug 299634 has been marked as a duplicate of this bug. ***

It seems that after the crash, I can no longer open up Kgpg. I am not sure if it is related or not.

That could be related to bug 298773.

You could look if there is a "default-key" line in ~/.gnupg/gpg.conf and if commenting out that line makes things better.

That line is already commented out. When run from a terminal, I get

$ kgpg
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
QDBusConnection: session D-Bus connection created before QCoreApplication. Application may misbehave.
$

It seems to be related to 298773. When I run kgpg, the process is running, but I get nothing to show up, and it sits there sleeping.

Those lines are totally unrelated (and from all that I know harmless). Are you sure KGpg isn't just hiding in the systray?

I can kill kgpg and then run it again, and I still get those same messages each time, and then the process just sleeps. I never get anything to show up after that crash.

Okay I feel dumb now. kgpg -k opened up the key management window I wanted to get to. However, it still won't open from the application launcher. At least I can get back to it now.

Actually, it seems that it did create the RSA 4096/4096 key I asked for, but it also made an RSA 4096/1024 key. I don't recall trying to make that key.

Seems to hit more people, so I take this as confirmed. Although I still can't see what's going wrong there.
