Bug 512504

*** This bug has been marked as a duplicate of bug 512500 ***

(In reply to Christian (Fuchs) from comment #0)
> SUMMARY
> Since the most recent update of Plasma Desktop (6.5.3) and KDE frameworks
> (6.20) plasma shell no longer starts cleanly, but is stuck in an eternal
> crash loop due to a segmentation fault in the calendar / akonadi
> integration. 
> This is highly critical, as the only way to get into a working desktop again
> is to edit the config file via the command line and commenting out said
> integration, regular users won't be able to do that. 
> 
> STEPS TO REPRODUCE
> 1. Update plasma and frameworks to the named versions
> 2. Have the akonadi integration (display calendar events in the digital
> clock calendar widget)
> 3. Log in
> 
> OBSERVED RESULT
> Eternal crash loop, desktop never starts
> 
> EXPECTED RESULT
> Desktop starts
> 
> Backtrace  (from a gdb session, since Dr Konqi spawned dozens of useless
> windows)
> 
> Thread 1 "plasmashell" received signal SIGSEGV, Segmentation fault.

What is the config file to edit? I have some suspect files in .config in home folder
