           Summary: Having no text in summary field of event dialog causes
                    lot of "Please specify a summary." dialogs to appear
                    leading to crash

Having no text in the summary field of an event dialog and continually clicking
the OK button brings up a lot of windows stacked on top of each other asking
"Please specify a summary.", if I then click on Cancel of the event window
underneath the dialog while all of these dialog windows are open, there is
another window asking "Do you really want to cancel?" If I click yes I am back
to a window with "Please specify a summary.", if I click OK on this I get a
crash.

Steps to reproduce:
1) Create a new event in korganizer with no text in the summary field, click
OK.
2) A dialog window appears with "Please specify a summary.", click the "Cancel"
button of the event editor window underneath this dialog window.
3) Another dialog window appears with "Do you really want to cancel?", click
OK.
4) In the "Please specify a summary." dialog, click OK on this and korganizer
crashes.

Notes:
Found this from unsuccessfully trying to reproduce bug #100691
Related to wishlist bug #132815
I could not find any other bugs similar.

I hope this is explained well enough to be understood and that I filed this in
the right place. Thanks for your time.
