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

I got a pdf attachment, clicked on it and got this crash.  When I restarted, went to the same email, clicked again, and the PDF opened in Okular as expected.

The crash does not seem to be reproducible.

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