Bug 305663

Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-23-generic x86_64
Distribution: Linux Mint 13 Maya

-- Information about the crash:
- What I was doing when the application crashed:

Kontact was the only program that I was actively running. The only software that was running that is not native to KDE or Linux-Mint was the Spideroak backup daemon. My KDE setup is essentially vanilla with no unusual option and very little changing of initial defaults (other than changes made by the Linux-mint devs). Nepomuk was not activated because I have noticed increased crashes and decreased performace when it is running. I had just added a series of "to-dos" in Kontact and noticed that I had missed some information on the last entry. Immediately after creating the incorrect to-do, I right-clicked the entry that I wanted to edit and immediately after the context menu appeared, Kontact crashed. I repeated this action several times and did not experience the bug again.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
