But now we have an explanation :) Can you reproduce this at will with the description you provided? Thanks 736358 2 rakuco 2009-03-29 16:35:32 +0000 Yes, I can, and it only happens to Kopete. If I have two or more Kopete windows grouped and choose not to allow them to be grouped, Plasma crashes. I don't know if it is really related to bug 188339, though, as I was not performing the same tasks in that bug report. 736455 3 aseigo 2009-03-29 21:40:04 +0000 yes, please mark all these bugs as dupes, and make this one the main report (given the nice "how to reproduce" comment). and if i were to guess, i'll bet it has something to do with destroying a group just when another item is about to be added to it or removed, as kopete often does due to chats coming and going. 736495 4 andresbajotierra 2009-03-29 22:38:34 +0000 *** Bug 188339 has been marked as a duplicate of this bug. *** 736500 5 andresbajotierra 2009-03-29 22:48:47 +0000 *** Bug 183818 has been marked as a duplicate of this bug. *** 736506 6 andresbajotierra 2009-03-29 22:51:33 +0000 *** Bug 184007 has been marked as a duplicate of this bug. *** 736508 7 andresbajotierra 2009-03-29 22:52:21 +0000 *** Bug 184358 has been marked as a duplicate of this bug. *** 736511 8 andresbajotierra 2009-03-29 22:54:21 +0000 *** Bug 187140 has been marked as a duplicate of this bug. *** 736513 9 andresbajotierra 2009-03-29 22:55:47 +0000 *** Bug 187368 has been marked as a duplicate of this bug. *** 736515 10 andresbajotierra 2009-03-29 22:56:04 +0000 *** Bug 187837 has been marked as a duplicate of this bug. *** 736517 11 andresbajotierra 2009-03-29 22:57:12 +0000 *** Bug 178076 has been marked as a duplicate of this bug. *** 737290 12 32514 remco.bloemen 2009-04-01 09:58:20 +0000 Created attachment 32514 Different backtrace I got a crash with a backtrace similar to bug 178076 when I closed a non plasma related window, I think it was konqueror.

HOW UNEXPECTED?!?!" Jay, this is out of line and is not acceptable behaviour in this community. bugs.kde.org is a resource we all share and one where calling people names is neither useful nor appropriate. Perhaps you could be the person who fixes it. Otherwise, be patient as we have been fixing and improving quite a lot of defects during this development cycle but haven't gotten to every single one. This one in particular is difficult as the problem is not only unobvious it's not easy to replicate. You may also wish to consider that your approach to venting has the exact opposite effect you hoped for. Please keep your comments constructive or keep them to yourself.

Hope I Helped 778564 60 gorgonz 2009-06-20 10:15:42 +0000 of course, this bug is an elder story, but i'm not sure about the right way to help. One can read, that the reasons are well known, while others say, that they have different failure presumptions. Is it still usefull to have more backtraces? 779599 61 aseigo 2009-06-21 21:28:53 +0000 SVN commit 984926 by aseigo: the task item pointer held on to during menus can be deleted on us, so use a QPointer; fixes some of the backtraces in the following reports: CCBUGS:193042,188378 M +7 -1 programgroupingstrategy.cpp WebSVN link: http://websvn.kde.org/?view=rev&revision=984926 779601 62 aseigo 2009-06-21 21:29:32 +0000 SVN commit 984938 by aseigo: don't delete the grouping strategy immediatley when changing it. this is due to the following possible chain of events: * window comes or goes * the grouping strategy is asked to update the groups based on this event, and tells the group manager about a change in events * the group manager notifies the outside world about it * the tasks widget's size changes becuase of this and that affects the optimal number of entries to show, which it relays to the group manager * the group manager realizes it now has enough room for all the tasks, and switches the grouping strategy ... BY DELETING THE GROUPING STRATEGY! * execution then eventually returns to wherever we were at step 2 ... BOOM (with all sorts of oddness in the backtraces :) this also explains why it was intermitent (change of grouping collection which caused a size change in the tasks widget which altered the optimal number of buttons) and only for some people ("only group when full" and with a variable size tasks widget, e.g. on an expanding panel) this is a pretty big set of changes, and i've gone over them carefully and tested them as thoroughly as i can, but additional feedback from people using SVN would be great as this is a big set of changes this close to release CCMAIL:plasma-devel@kde.org
