Description nydel 2013-11-30 17:33:03 UTC
Application: dolphin (4.11.2)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

dragging a .avi into vlc media player. vlc was not doing anything. there's plenty of memory and cpu etc, this happens a lot, it's certainly a bug

- Unusual behavior I noticed:

when i drag the file to vlc, vlc automatically plays it and goes fullscreen. sometimes, and i can't duplicate this though i bet it is possible to duplicate, a modal/popup thing that lists the directories preceeding the directory i was in -- i could click one of the directories if i want and the window or tab i'm using in dolphin would navigate to that folder.  i don't know how to make this menu appear, but it happens sometimes when i drag something into vlc and dolphin often crashes within a few seconds after that (the menu is visible atop the fullscreen vlc player even though dolphin is behind it).

The crash does not seem to be reproducible.

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

i wanna add (in case helpful) that desktop effects are enabled and working, and dolphin /may/ have been slightly transparent but has no application-specific window appearance specifications
Comment 2 Christoph Feck 2013-11-30 18:15:13 UTC
This could also be bug 293863, but those do not have Oxygen in the backtrace.
Comment 3 Hugo Pereira Da Costa 2013-11-30 18:40:23 UTC
@Christophe
Thanks for posting the other report.
In fact I have also seen weird behaviors and crashes in my own qt apps with drag and drop.
My "gut" feeling is that there is something broken (and unreproducible unfortunately) in current Qt4 drag and drop ...
Comment 4 Christoph Feck 2013-12-02 00:04:37 UTC
Yes, drag and drop in Qt is dangerous, because it uses a local event loop. This unfortunately is not changed for Qt 5.

New crash information added by DrKonqi

dolphin (4.13.0) on KDE Platform 4.13.0 using Qt 4.8.6

- What I was doing when the application crashed:

Likewise, I had just dragged a folder of MP3s into vlc's playlist, and dolphin crashed a couple seconds later.
