Kontact crashes often when trying to select an addressee via the address book, for a mail sent via Kmail.

Hello Everybody.

Today, Tuesday 7 March 2017, I have submitted bug nr. 377338 at bugs.kde.org:

Kontact crashes often when trying to select an addressee via the address book, 
for a mail sent via Kmail.  

Please, check the details here:

https://bugs.kde.org/show_bug.cgi?id=377338

I need to restart and retry several times before I can pick an address from 
there and send the mail.  

In the bug report, you can find three .txt files. Each file is a report generated 
by the command line, after starting Kmail from there. By doing so, I try to 
provide you with info from three crashes that have happened today, 7 March 
2017. However it may be  I have been stumbling on this problem already a few 
months.

Can you help me to fix the problem or at least to find some reasonable 
workaround?

Yours.

Bas G. Roufs.
