Version: (using Devel) Installed from: Compiled sources Very strange. It doesn't happen with regular kwin at all. beta8, suse packages. libqt4-4.4.3-29.1 Steps to reproduce: drag a picture from an album (ie using regular folder-based album view) on to another app (ie dolphin). Either alt-tab with maximised windows or just drag it off the digikam window if not maximised. drag it around a bit without releasing dolphin crashes: Program received signal SIGSEGV, Segmentation fault.

KDE4.2 Opensuse packages, KWin desktop effects enabled (XRender, only few effects enabled). No crash here. Will, can you reproduce with current Opensuse packages? Does this depend on OpenGL? Does this depend on certain KWin effect modules enabled (which do you have enabled?)?
Using Archlinux with latest KDE4.2 packages, KWin with OpenGL (but I also tested XRender): No problems when dragging images from digiKam to dolphin or konqueror.
Kubuntu 8.04 with ppa repo and KDE4.2: Crash while dragging, but composite disabled.

sorry, kubuntu 8.10 was it
i can't reproduce with kde 4.2.2, Qt 4.5 and digikam 0.10 final can you still reproduce ?
Will, does it still crash for you? Can you give us an update here? Andi
(In reply to comment #6) > Will, > > does it still crash for you? Can you give us an update here? > > Andi No. I had updated to Kubuntu Jaunty in the meantime.
So it is "fixed"... I will close this one now. Thanks for the update! Andi
