Description Bartosz Gęza 2009-03-02 17:28:46 UTC

Version:           2.2.0 (using KDE 4.2.0)
Compiler:          gcc 4.3.3 
OS:                Linux
Installed from:    Gentoo Packages

When in View mode experienced a crash after switching to parent dir. 

Dir structure:
dir1/
dir1/subdir

In each directory there is one image (JPEG image data, JFIF standard 1.02)
I'm browsing dir1/subdir, I click on the image, then I press Alt+Up or choose parent dir from menu, then crash occurs.

Comment 1 Aurelien Gateau 2009-03-02 19:39:23 UTC

It works for me... both trunk and 4.2. But I am using Qt 4.5, maybe that's the difference.

My version of Qt is 4.5.0-rc1
I've successfully reproduced this bug on another user's Gentoo laptop.
