Description Panagiotis Papadopoulos 2009-05-09 16:32:02 UTC
Application that crashed: dolphin
Version of the application: 1.2.80
KDE Version: 4.2.85 (KDE 4.2.85 (KDE 4.3 Beta1))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-ARCH i686

What I was doing when the application crashed:
I just found this pretty hard to reproduce crash ;-)

1. Open Dolphin move to a folder (e.g. /home/user/test) with some subfolders and enter one of those subfolders (e.g. /home/user/test/test1
2. Drag an audio file on the little arrow on the bread crumb bar and drop the file on another subfolder (e.g. /home/user/test/test2), select "Copy"
3. Redo step 2 again
4. The "File already exists" dialog will appear,  select "Overwrite" (this also reminds me of my other wish https://bugs.kde.org/show_bug.cgi?id=190471)

Dolphin should crash now. If it doesn't, you might have to try these steps several times, with different files and directories to get Dolphin crahsed.

Here on a recent version of trunk.

Thank you

I again tried to reproduce it and got the following backtrace. This time it was a lot harder to reproduce it, I had to try it very often...

Comment 2 Dario Andres 2009-10-03 21:46:28 UTC
I think managed to reproduce this crash here using:

Qt: 4.6.0 (Qt git branch 4.6 commit f3d15516572394b6bcd44a89dd66516fa4eba56e
        Date:   Fri Sep 25 10:21:23 2009 +1000)
KDE: 4.3.70 (KDE 4.3.70 (KDE 4.4 >= 20091002))
kdelibs svn rev. 1030916 / kdebase svn rev. 1030916
on ArchLinux i686 - Kernel 2.6.30.6

---

In order to reproduce it I had to disable the Plasma filejobs tracking (so file operations will use the old-style dialogs)
After the "Overwrite" dialog appeared, I wait some seconds, and then I clicked the "Down arrow" in the copy dialog (the one that will show more info). (it is a false click as the Overwrite dialog is modal.. the file-copy dialog is not accesible).
Finally clicking the Overwrite button crashed Dolphin

---

When I tried to reproduce this I also got a backtrace similar to bug 200148, so they could be related.

----

Darn, I'm getting different backtraces in a non-reproducible way.. :-\

Comment 3 Jeroen van Meeuwen (Kolab Systems) 2012-08-24 16:18:34 UTC
Resetting assignee to default as per bug #305719
Comment 4 Jaime Torres 2012-10-27 08:51:12 UTC
The backtrace is totally different, but following the steps described here, dolphin still crash.
See bug 309076
Comment 5 Frank Reininghaus 2013-07-02 17:31:50 UTC
Git commit 669ee3250d233b96bc2f2e63865b048d33215674 by Frank Reininghaus.
Committed on 02/07/2013 at 17:27.
Pushed by freininghaus into branch 'master'.

Fix crash when dropping URLs on the URL navigator's drop down menus

The problem was that the files were copied/moved inside the nested event
loop of the drag, which caused problems if the "File exists" dialog was
shown.

The solution is to make the copy/move operation delayed, such that it is
executed in the main event loop.

Note that dropping files on these menus does apparently not work at the
moment when using the Oxygen style (see bug 310016).
