Bug 336687

Application: kmail (4.12.5)
KDE Platform Version: 4.12.5
Qt Version: 4.8.6
Operating System: Linux 3.14.8-200.fc20.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

See the bug report for #311184 as I did a write-up of my background of how I arrived at this situation.  Essentially, I am on GNOME Shell v3.10.2 (Fedora 20, 64-bit) and I am using KMail v4.12.5, and I was unable to use the full e-mail search capability (the binoculars icon).  So, I ran the "nepomukserver" command in terminal to make the full search dialog actually work.  However, this is where this bug comes in, after I type something for the search dialog to look for and right when I click on "Search", KMail crashes from a segmentation fault.

The crash can be reproduced every time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
