Description Arkadiusz Miskiewicz 2010-12-17 20:27:32 UTC 
Application: kmail (1.13.5)
KDE Platform Version: 4.5.4 (KDE 4.5.4)
Qt Version: 4.7.1
Operating System: Linux 2.6.37-rc6-00009-gb3444d1 x86_64

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

I'm composing new mail, clicking to add attachment, "open file" picker shows up. Assume the file I want is in /home/arekm/Desktop/somewhere/file.txt and I'm in /home/arekm. So I start typing "Des" in file picker form, hint for "Desktop" name shows up. Then I press "End" key to go to end of text in that form and kmail crashes then.

Easy to reproduce here.

The crash can be reproduced every time.

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