Bug 263106

Application: dolphin (1.5)
KDE Platform Version: 4.5.5 (KDE 4.5.5) "release 1"
Qt Version: 4.6.3
Operating System: Linux 2.6.34.7-0.7-desktop x86_64
Distribution: "openSUSE 11.3 (x86_64)"

-- Information about the crash:
Moving a bunch of jpeg files from one dolphin window to another.
At least, in this case, the crash is in Qt code so it might be locatable.
Line is
l.1624    if (target) {
...
l.1633        move.data.l[0] = dragPrivate()->source->effectiveWinId();

The crash can be reproduced some of the time.

-- Backtrace:
Application: Dolphin (kdeinit4), signal: Segmentation fault
