Description Miroslav Ľos 2009-08-14 22:20:24 UTC 
Version:            (using KDE 4.3.0)
Compiler:          gcc (Gentoo 4.3.2-r3 p1.6, pie-10.1.5) 4.3.2 
OS:                Linux
Installed from:    Gentoo Packages

Steps to reproduce:
1. Open Dolphin in a folder with two movies ready and KMplayer side-to-side.
2. Play one video in KMPlayer. Skip a few seconds into the end of the file.
3. Drag the other video from Dolphin over KMPlayer's video area, but never drop it. The drop operation should be unavailable over the embedded mplayer's window.
4. Wait hovering until the movie ends. Then try moving the mouse (still dragging!) to Dolphin and back to KMPlayer. This crashes both apps reliably for me.

Both backtraces follow. The backtrace for Dolphin looks similar to that of bug #200583, but in my case no alt-tabbing takes place and the crashes are also reproducilbe with Desktop Effects disabled.

Backtrace for Dolphin (locals cut from frame 10 on):

New crash information added by DrKonqi

ark (2.15) on KDE Platform 4.5.5 (KDE 4.5.5) using Qt 4.7.0

I was trying to extract firefox (tar.bz2) from ark to thunar in xcfe.
When selecting all the subfolders and dragging to thunar, both thunar and ark crashed.

Comment 76 Ralf Habacker 2011-10-09 21:42:48 UTC 
In kmymoney crashes in QWidget::testAttribute_helper has been found too (https://bugs.kde.org/show_bug.cgi?id=283538) 
 
In that case an already free'd QWidget object which content is referenced in the following line raises the access violation 

    return (d->high_attributes[int_off] & (1<<(x-(int_off*8*sizeof(uint)))));

To identify such cases the object the this pointer points to should be inspected. If the related object contains valuable content, this is propably not this case. 

msvc build in debug mode for example shows a 0xfeeefeee as content of free'd object e.g. QWidget::data.

Comment 78 Nick Shaforostoff 2012-02-24 19:11:41 UTC 
i can reproduce this bug when i switch windows with alt+tab (kwin effects enabled) while dragging. dolphin crashes when i release all keyboard keys.

i noticed 'xdndHandleBadwindow returned true' string in konsole output of dolphin

Comment 80 Nick Shaforostoff 2012-02-24 19:18:14 UTC 
anybody objects to closing this bug as duplicate of bug 192270 ?
Comment 81 Miroslav Ľos 2012-02-25 00:27:14 UTC 
I fspecifically filed this bug as separate from bug 200583 (now duplicate of 192270) to emphasize that the bug is neither dependent on alt-tabbing nor desktop effects. I find this report is more general, with a more fitting title and uses a more verbose backtrace. Comment #4 in that bug is probably worth keeping around though.
Comment 82 Nick Shaforostoff 2012-02-27 13:19:25 UTC 
it seems i have fixed the crash, it is a one-line fix in Qt, see my comment in QTBUG-19363
Comment 83 Christoph Feck 2014-04-13 13:10:33 UTC 
Fixed upstream since Qt 4.8.4.
