Comment 20 for bug 862220

It was reported for my by a Windows user that after he created a personal calender ical ressource on an external memory stick he ran into that Problem.

We really need to handle this error case (Akonadi has a ressource configured but cant access the data for whatever reason) far more gracefully then just shutting the GUI down.
I am setting this to Major severity and personally think this bug should even be critical because it makes Kontact completly unusable until the user finds some way to edit the configuration. The Error message does not offer enough information with regards to what is really broken. So most of the users will face the impossible situation that they just can't use their Groupware Suite anymore after the configuration got somhow out of sync with the actual data.
