--- Comment #2 from Matthias Kretz <kretz at kde.org> ---
I just got a very similar crash backtrace on the following activity:

* new mail
* click 'Select' button on To: field
* the dialog opens and is unresponsive, waiting for the contact data to come in
(this blocking UI - and the time it takes might be worth a bug report itself).
* the dialog shows the contact data for half a second
* crash

## Comment on the backtrace

The `0x0` in `#31 QCoreApplicationPrivate::sendPostedEvents
(receiver=receiver at entry=0x0` looks suspicious.

## Backtrace

Application: Kontact (kontact), signal: Segmentation fault
