Isn't there something missing?
While I was hacking on improving KGpg status output when generating a key I found some behaviour in the plasma progress bar that first confused me (as I thought my messages were not working at all) and now I think it's just a bug.
As you can see right of the application icon there is no description shown for an already running job. Once it is finished the description is shown there. I found out that this wasn't my fault as the dolphin progress bar showed the same behaviour when I was copying some large files from my brothers computer.
I'm using KDE 4.3.3 (yes, I'm lame) and would appreciate any hints on if that's intended, if there's a bug report, or anything else that would allow me improving this. My mail address is in your KGpg about box ;)
