Bug 349299

Application: kmail (4.14.8)
KDE Platform Version: 4.14.8
Qt Version: 4.8.6
Operating System: Linux 3.19.2-1-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

I entered a search string in the quick search field above the message list - no matching mail was found in this folder, so I clicked on the search action to get the search window for selecting other folders, but kmail crashed

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
