Bugzilla Bug 261162

After adding a calendar resource to korganizer, de-selecting and re-selecting
it in the Show Resource View sidebar causes its entries to appear multiply.

Reproducible: Always

Steps to Reproduce:
1. Import an .ics calendar into KOrganizer
2. De-select the calendar in the Show Resource View sidebar
3. Select the calendar in the Show Resource View sidebar

Actual Results:  
Each deselect-reselect cycle duplicates all the entries in the calendar.

Expected Results:  
The entries in the calendar should not be duplicated.

emerge -pv korganizer                                                          
                                  (03-04 23:46)
