Bug 458849

SUMMARY
After clicking on an event that includes a location the location is loaded. But after clicking on another event while kalendar is still loading the location it segfaults. The KDE crash handler was unable to generate a backtrace so I tried using gdb, I've never used it before so I hope the information is useful :). The bug doesn't occur when maps are turned off. Is there any other information I could provide that could be useful?

STEPS TO REPRODUCE
1. Create an event with location data and have map viewing enabled
2. Click on the event 
3. While the location is still being loaded (you have to be pretty quick) click on another event 

OBSERVED RESULT
Kalendar segfaults

EXPECTED RESULT
The other event should be displayed without kalendar crashing
