Bug 295918

Application: konversation (1.4)
KDE Platform Version: 4.8.1 (4.8.1)
Qt Version: 4.8.0
Operating System: Linux 3.2.0-17-generic x86_64
Distribution: Ubuntu precise (development branch)

-- Information about the crash:
Kubuntu 12.04b precise amd64, KDE 4.8.1 and Konversation 1.4 from Canonical main repositories. Akonadi and Nepomuk is disabled by modifications to ~/.config/akonadi/akonadiserverrc and ~/.kde/share/config/nepomukserverrc respectively.

- What I was doing when the application crashed:
I started Konversation but found that the server list did not automatically show up as it was configured to be. Being impatient, I manually opened the server list and tried to connect, upon doing which I experienced this crash. It also appeared that the quick connect dialog could not be opened at all.

- How to reproduce:
1. Set Konversation to automatically open the Server List upon startup, then exit
2. Disable Akonadi (and Nepomuk) and make sure to kill any of their running processes
3. Start Konversation, observe that the server list does not show up immediately
4. Open the server list manually and connect to a server

- Expected results:
5. Connection procedure starts normally

- What actually happened:
5. Crash with this backtrace

- Additional information:
It turns out the server list *did* automatically show up -- but only after waiting fairly precisely 30 seconds. Connecting at that point worked without issue and the quick connect dialog could also be opened normally.

I enabled debug output in kdebugdialog and started konversation via the terminal. As usual I got the normal akonadi/mysqld traceback that all Akonadi-aware KDE applications output, but when the server list finally displayed it also said the following;
>"akonadiserver" crashed too often and will not be restarted! 
>konversation(4099)/libakonadi Akonadi::Control::Private::exec: Could not start/stop Akonadi! 
>konversation(4099)/kresources: Failed to start Akonadi 
>konversation(4099)/kdepimlibs (kabc): "Unable to open resource 'Akonadi Contacts'."

It seems that Konversation gives Akonadi ~30 seconds to start up before automatically showing the server list. If you try to connect before it timeouts, it crashes.

The crash can be reproduced every time.

-- Backtrace:
