Bug 363396

Application: kontact (4.14.10)
KDE Platform Version: 4.14.17
Qt Version: 4.8.7
Operating System: Linux 4.4.9-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
Having an oddly recurring event I decided to copy the original and paste subsequent instances of it.
Firstly, on pasting the subsequent event does not show up on the date pasted to.
Having tried this before and found that the subsequent event has been created but simply hasn't been shown, I decided to close and reopen KDEPIM.
With either a single or multiple pastes, KDEPIM crashes on close.
I have done this two or three times with a crash every time.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
