Description nichtbekannt 2012-08-06 13:29:50 UTC

Application: dolphin (2.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic-pae i686
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I moved files in dolphin from one tab to another. If i have more than 2 tabs open in dolphin and i move files between them, i can practically wait for a crash to occur. Not immediatly, but it will happen. So it is basically reproducible. I had Firefox, Thunderbird, KompoZer and rekonq opened at the time of the crash.

The crash can be reproduced some of the time.

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

Comment 1 Frank Reininghaus 2012-08-07 15:45:46 UTC

Thanks for the bug report! How exactly do you move the files (drag&drop, cut&paste, ...)? Does it only happen when moving multiple files? Does it depend on the file type? Am I assuming correctly that the crash does not happen if you disable the Information Panel?

Comment 2 nichtbekannt 2012-08-07 16:58:54 UTC

I move files via drag and drop. I've seen it crash with only a single file moved. And the file type seems not to be relevant, because it happens with mp3's, video files and pictures too. I wasn't able to produce this error with the information panel turned of.

Comment 3 Jeroen van Meeuwen (Kolab Systems) 2012-08-24 16:21:33 UTC

Resetting assignee to default as per bug #305719

Comment 4 Frank Reininghaus 2013-04-26 12:53:02 UTC

Does this still happen in KDE 4.10.2 or later?

Comment 5 nichtbekannt 2013-05-04 11:51:39 UTC

> Does this still happen in KDE 4.10.2 or later?

From my stint with KDE version of ManjaroLinux, i didn't encounter this bug there. Since it  was a tad unstable i'm using Kubuntu again, which i upgraded to 13.04 just an hour ago. So i can't give you no upgrade for this Distro yet.

Comment 6 Frank Reininghaus 2013-05-12 08:48:12 UTC

Thanks. Please let us know if this happens again and you can provide more information. We could then forward this to kdelibs (because the crash happens in kdelibs code).

Comment 7 Julian Steinmann 2018-03-30 15:28:57 UTC

Closing now as this seems fixed with KDE 4.10.2.
