Version: unknown (using 4.1.67 (KDE 4.1.67 (KDE 4.2 >= 20080918)) "release 1.2", KDE:KDE4:UNSTABLE:Desktop / openSUSE_11.0) Compiler: gcc OS: Linux (x86_64) release 2.6.25.16-0.1-default On plasma start binary clock shows its internal containment ( context menu calendar) and when you move it, this containment separates from widget. Often when you remove widget in this state - it crashes plasma. This behavior don't occur in analog clock. I'll try to make a screenshot.
Created attachment 27524 [details] plasma binary clock widget bug
This binary clock widget also displays white text "no items".
You need to add the backtrace of the crash please. Look here: http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports to create a useful report, thanks in advance!
some output from gdb, when mousemove event cause segfault in plasma. I hope it's helpful. Do you need valgrind log? "Program received signal SIGSEGV, Segmentation fault.

The only way to get rid of calendar window, is to move it in unlock mode, right click->remove. But it returns after login, of course.
Can't reproduce it from several days, so marking as fixed. In case it is not for you, please feel free to re-open it. =)
*** Bug 173192 has been marked as a duplicate of this bug. ***
There is a dupe of this and bug 172671 looks closely related, I think it should be re-opened for now.
This looks like it is bug 170175 and bug 170564. But its still being seen with qt 4.4.3 on openSUSE 11.1. See https://bugzilla.novell.com/show_bug.cgi?id=440118
*** Bug 174079 has been marked as a duplicate of this bug. ***
Rob: is this still an open issue?
Are you sure this is related to #173192? This relates to the extender, but the other bug relates to removing the actual applet. I am using 4.1.73 and do NOT see this bug (I used to see it a few revisions ago), but I still get the removing widgets crashes plasma problem. It seems that #173192 IS (possibly) related to #172671 but they are not related to this one, I can still replicate both of them.
still crashing with svn: 886841 similar to the previous bt, not sure its the same, so posting here: Application: Plasma Workspace (plasma), signal SIGSEGV Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

this should be fixed in trunk, does it still happens? the crashing on close looks like a qt bug fixed in qt-copy
still happening with qt svn: 886727, kdetrunk svn: 887466
Seems fixed in recent trunk. Probably commit 891037 fixed it
Can somebody else who experienced this problem confirm it has been fixed?
Yes I can still confirm this crash happens with svn trunk build from about 8 hours ago.
@SlashDevDsp: If that is the case, could you provide an up to date backtrace? And which version of qt are you using? One crash that could occur when detaching an extenderitem has been solved in qt-copy.
Created attachment 29061 [details] backtrace of plasma >= 2008-12-04 kdebase rev 892566 kdelibs rev 892430

can you install qt-copy and apply the patches please? slashdevdsp: are you using qt-copy with patches?
kde and qt-copy with patches svn: 892691. This is what happens now, I tried to move the calendar out from the clock to the desktop and plasma crashes, with no crash dialog for a backtrace. I will try to get one with gdb soon.
Ignore my previous comment about plasma crash dialog not being generated, when plasma crashes i get the crash dialog, and here is the updated backtrace.

Confirmed with trunk compiled some minutes ago. This is for me 100% reproducable on trying to e.g. close the digital clock applet pressing the x on the applethandler (same with analog clock and most other applets).

this is an upstream bug in Qt. they have fixed it upstream. the fix needs to percolate down .. via Qt.
Yeah, I also thought it was an upstream bug, since with my up to date qt-copy it doesn't occur. What still worries me though, is that there are apparently people with an up to date qt-copy that report this bug. Or is this problem still in qt-copy and does it just not show up for everybody?
Aaron, does that mean the fix is not in qt-copy in trunk yet? I will try to update and do a clean build of everything qt-copy/kdelibs/kdebase etc. tonight and report back.
ok updated about 10 hours ago, qt-copy svn: 889120, kdebase: 894691, kdelibs: 894713 and the plasma crash still happens. This is after deleting all existing builds and doing a complete reconfigure (make clean) and i still get a crash when trying to move the calendar extender from the digital clock applet in the panel to the default desktop containment. latest bt below: Application: Plasma Workspace (plasma), signal SIGSEGV Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

Notice that there are 2 different bt's in this bugreport and it's comments. I think one is the qt bug that got fixed, and the other didn't get fixed but doesn't happen for everyone. I had a similar crash though when making an otherwise seemingly unrelated change, and fixed that crash in that same revision. So r895118 might solve this issue for the people who still have the problem. Could someone experiencing this crash please test this?
seems like there is a partial fix. This is what happened. I can move the extender calendar from the panel digital clock to the desktop without crashing plasma. Then I closed the calendar and tried to move the calendar extender again from the panel digital clock, did this a few times and bam crash again. bt below: Application: Plasma Workspace (plasma), signal SIGSEGV Using host libthread_db library "/lib/tls/i686/cmov/libthread_db.so.1".

I am also still seeing a crash, not sure if it is the same as the initial report or even comment #35. I am using qt-copy (which seemed to fix the consistent crash) and nvidia 180.06. This crash is caused by dragging out the calendar, closing it and then repeating about 8 times.

Hmm, someone noticed that this bugreport now has 4 different bt's of which 2 now apparently are fixed, and 2 others have taken their place? And still i can't reproduce any of them :'( Anyway: could you details this new crash some more? Does the crash happen while dragging? after releasing the mouse button? how do you 'close' the extender (return-to-source icon on X on applet handle). Any details would be welcome.
well i closed the calendar extender applet with the close button that gets displayed when mouse over applet. There is also another close-button-built-into-the-calendar-applet. I did try to close with that one too a few times, just before the crash i closed the calendar applet using the close button that gets displayed for all the other applets. another problem is, if you resize the calendar applet i.e., make the size/applet bigger you cannot make the size smaller.
I am closing with the plasma close button that pops out. I thought the other button was a reattach button. I have a xinerama setup, I sometimes drag over to the other monitor but the crashes seem to happen on the same screen as plasma. I just had another crash while dragging (ie. before releasing the mouse) but no backtrace appeared this time. This last crash left me with an empty containment on the desktop which was initially sized for the calendar, as soon as plasma had fully started it resized it to a small circle.
Here is the output from plasma as it crashes. It sometimes takes a lot of opening and closing to reproduce it. The 'in wrong parent' message appeared every time I dragged the calendar out. The 'Invalid size' message was when I dragged it back to its original containment.

ok, this is how i can reproduce the bug every single time now. I wrote lengthy paragraphs about reproducing the bugs, then i realised its getting too complicated, i just recorded my desktop and here is the link: http://rapidshare.com/files/172082378/out.ogv.html one thing to note is that after removing the calendar I try to put it back into the same container as shown from 8sec in the clip until 11sec thus producing the crash at 16sec. I hope this is clear.
@SlashDevDsp: sweet :) thanks for the video, I can now reproduce this bug myself. I also think I know what's causing it. I first have to do some other work now, but expect a fix later today or tomorrow.
Btw, I think this is the same bug that Mike is having when moving the applet from the desktop on one monitor to the 2nd monitor desktop. i.e., the applet gets detached from the firstdesktop and gets attached to the same? container in the 2nd desktop. fantastic Rob :) finally i can see this bug being closed :) hurray...
SVN commit 895405 by scheepmaker: Yeah, finally! Fixed a crash that occurs when moving an extenderitem back to its source from an extender that was also the last one to have a spacer inserted because the same item was hovering over it. Phew, that was a mouthfull... With this fix we monitor if previousTargetExtender get's destoryed so we don't accidently try to remove it's spacer. BUG: 171498 M +16 -0 extenderitem.cpp M +1 -0 extenderitem.h M +1 -0 private/extenderitem_p.h WebSVN link: http://websvn.kde.org/?view=rev&revision=895405
with the latest svn build, plasma does not crash, but dragging the calendar extender to the desktop it just disappears, without staying on the desktop.
You don't have your widgets locked by any chance?
yes you were right, i had the widgets locked. What should be the behaviour when the widgets are locked? I certainly assumed it is a bug. When it is not locked though it works without crashing :)
What the behavior should be, and is here, is that the item returns to where it came from. Maybe I should pop up the extender again when that happens to make it clearer. Anyway, thanks for confirming.
I ended with a similar crash using: Qt: 4.4.3 KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2)) kdelibs svn rev. 896338 / kdebase svn rev. 896338 while trying to reproduce bug 168427 (and may be , de-attaching the "buggy moving file dialog/plasmoid" or may be related to bug 168427 itself.) I don't know if it's related to the original bug report, but it's similar to the one in comment 36 Here is the backtrace: Application: Plasma Workspace (plasma), signal SIGSEGV 0x00007ff4f1791ed1 in nanosleep () from /lib/libc.so.6 [Current thread is 0 (LWP 23992)] Thread 3 (Thread 0x411b5950 (LWP 23993)): #0 0x00007ff4f21f7d49 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/libpthread.so.0 #1 0x00007ff4f2466b55 in QWaitCondition::wait (this=0x1ba7580, mutex=0x1ba7578, time=18446744073709551615) at thread/qwaitcondition_unix.cpp:82 #2 0x00007ff4f5a3bde4 in QHostInfoAgent::run (this=0x1ba7560) at kernel/qhostinfo.cpp:241 #3 0x00007ff4f2465f99 in QThreadPrivate::start (arg=0x1ba7560) at thread/qthread_unix.cpp:185 #4 0x00007ff4f21f3fe7 in start_thread () from /lib/libpthread.so.0 #5 0x00007ff4f17c223d in clone () from /lib/libc.so.6 #6 0x0000000000000000 in ??

@Dario, That specific crash was a Qt bug which is solved in qt-copy.
just for the record; * the patch that fixes it in qt-copy is 0254-fix-qgraphicsproxywidget-deletion-crash.diff * it should be part of Qt 4.4.4 as addition to my comment #28 following is a better workaround and less java-like :)~ Index: kdebase/workspace/plasma/applets/systemtray/ui/notificationwidget.cpp =================================================================== --- kdebase/workspace/plasma/applets/systemtray/ui/notificationwidget.cpp (revision 897269) +++ kdebase/workspace/plasma/applets/systemtray/ui/notificationwidget.cpp (working copy) @@ -145,6 +145,12 @@ actions.clear(); actionOrder.clear(); + if (actionsWidget) { + foreach(QGraphicsItem *childitem, actionsWidget->childItems()) + if (QGraphicsProxyWidget* proxy = dynamic_cast<QGraphicsProxyWidget*>(childitem)) + proxy->setWidget(0); + } + delete actionsWidget; actionsWidget = 0; }
