Version: 1.3 (using KDE 4.3.3) OS: Linux Installed from: Ubuntu Packages Steps to reproduce: 1. Open dolphin and navigate to a folder containing multiple other folders 2. Click on one of the folders 3. Click and drag a file onto the down arrow next to the parent folder in the navigation bar 4. Let go of the mouse button and as soon as the move/copy menu appears click twice (with a slight pause in between clicks) in the white space in the dolphin window to cancel the action. 5. Dolphin crashes.

Thanks for the report. This looks like a Qt/X11 issue. Could you please tell us which Qt version you have? Did you specify a specific render target (OpenGL, XRender)?
I'm using qt v4.5.2 on Kubuntu 9.10 amd64. The qt package versions are listed as 4.5.3 but the libraries are still named 4.5.2. libqt4-core (4.5.3really4.5.2-0ubuntu1) I installed the kde 4.3.4 packages from the Kubuntu Updates PPA. deb http://ppa.launchpad.net/kubuntu-ppa/ppa/ubuntu karmic main
This could be related to the glibc bug : bug 196207. Check this: - Quit Dolphin - Start Konsole - Type "export QT_NO_GLIB=1" + Enter - Type "export MALLOC_CHECK_=" + Enter - Type "dolphin" + Enter - Use Dolphin and check if it crashes or not If it doesn't crash, then it is likely to be bug 196207.
I tried the steps listed above and unfortunately dolphin still crashes. Application: Dolphin (dolphin), signal: Segmentation fault The current source language is "auto; currently c".

I forgot to tell that the second backtrace was a bit different than the first one.. but it should be related if the situation is the same.
*** Bug 230481 has been marked as a duplicate of this bug. ***
I could not reproduce an immediate crash after following the steps, but still there is a crash after closing Dolphin when doing this. I've set the status to "NEW".
I just tested this bug in KDE 4.5.0 and I couldn't seem to reproduce the original bug but I did encounter what appears to be a different bug/crash while following the same steps described in the first post.

(I quickly reviewed the backtrace of this crash, and it appears to be caused by KIconCache memory corruption. If this is not the case, please reopen.) Closing all KIconCache crashes as fixed, because the KIconLoader in KDE SC 4.5 now uses KSharedDataCache to cache icons, and it is believed that the new class is less prone to random crashes or memory corruption. If you still can reproduce a crash with version 4.5, please report it separately. If you cannot upgrade to 4.5 yet, you should be able to work around this crash by deleting the icon cache files in /var/tmp/kdecache-<user>/kpc
