Description Andreas Bank 2009-10-07 11:25:05 UTC

Version:           0.10.0 (using 4.2.4 (KDE 4.2.4), Kubuntu packages)
Compiler:          cc
OS:                Linux (i686) release 2.6.28-15-generic

Hi,

while dragging pictures from digikam to another application digikam and the other app crashes. Here is what i do.
1.) Start dragging the picture
2.) Toggle the application (Alt + Tab)
3.) Drop the image

The crash occurs during the toggling and does not occur during every drag-and-drop. But once in 10 times.

Here the crash report:

Comment 1 caulier.gilles 2009-10-07 11:37:59 UTC

I think it have been fixed in current implementation from svn. Please try again with digiKam 1.0.0-beta5

Gilles Caulier

Comment 2 Andreas Bank 2009-10-07 12:08:19 UTC

Hi Gilles,


thanks for the quick reply.
I'll check the latest version today.

By the way, I allways wanted to say thanks to you for this great peace of 
Software!
I really love Digikam!

All the best.

Andi

Comment 3 Dario Andres 2009-10-09 01:22:23 UTC

- Are you using Desktop Effects / Compositing ? There are know Qt drag&drop bugs while alt-tabbing which could trigger such a crash 
Thanks

Comment 4 caulier.gilles 2009-12-25 20:07:28 UTC

digiKam 1.0.0 is out since few days...

http://www.digikam.org/drupal/node/491

Please try with this version coming with more than 400 bug-fixes.

Thanks in advance

Gilles Caulier

Comment 5 caulier.gilles 2010-01-25 21:49:38 UTC

digiKam 1.1. release will be done in few days. Please check if this entry still valid.

Thanks in advance

Gilles Caulier

Comment 6 caulier.gilles 2010-04-04 10:44:03 UTC

digiKam and Kipi-plugins 1.2.0 are out. Please check if crash is still valid there.

Thanks in advance

Gilles Caulier

Comment 7 Jonathan Verner 2010-09-07 15:09:55 UTC

I can reproduce it with digikam 1.4.0 and KDE 4.5.1. When doing drag-and-drop to inkscape (possibly also other apps, not tested) AND using Alt-Tab, digikam crashes when I release the Alt-Tab key with the backtrace shown below. When doing just drag-and-drop without the Alt-Tab switching, everything works fine.
Also, when I disable desktop effects, everything works fine, which would seem to indicate a qt bug (see comment #3)

This is the output from digikam:

xdndHandleBadwindow returned true
QSocketNotifier: Invalid socket 36 and type 'Read', disabling...
QSocketNotifier: Invalid socket 39 and type 'Read', disabling...
QSocketNotifier: Invalid socket 42 and type 'Read', disabling...

This is the backtrace:

Comment 10 Javier Conti 2010-12-05 14:07:47 UTC

Created attachment 54157 [details]
New crash information added by DrKonqi

digikam (1.5.0) on KDE Platform 4.5.4 (KDE 4.5.4) "release 3" using Qt 4.6.3

- What I was doing when the application crashed:

I dragged a picture, pressed ALT+TAB bringing kflickr on top, then dropped the picture into it. Quite often, but not always, digikam crashes.

-- Backtrace (Reduced):

Comment 11 Jonathan Verner 2010-12-15 12:37:24 UTC

When I have time, will try to compile digiKam 1.6 and test it.

Comment 12 Marcel Wiesweg 2011-01-18 14:18:05 UTC

There are similar reports all over KDE. Seems to be a Qt bug really.

*** This bug has been marked as a duplicate of bug 192270 ***

Comment 13 caulier.gilles 2019-08-14 18:52:48 UTC

Fixed with bug #192270
