my system setup in such a way that it would only use QT's debug libraries. Right now it is undefined which one is used, which leads to crashes during debugging described here: http://developer.qt.nokia.com/forums/viewthread/6748/
To answer your questions Teo: > 1) Is there a way you can install debug symbols for Qt and KDElibs?

Our goal is to > get something better than "No symbol table info available." in those > backtraces. I know, and I'll try to do what's needed. > I'm the developer who created the new About dialog so I > can try and guess what goes on, but without a better backtrace it will > be hard to figure this out. Great to see that I finally got into direct contact with the original author. :-) > 2) I see you submitted various reports with two different backtraces > in those links so I don't understand, does the crash happen when you > click on one of the elements of the view or just when you close the > dialog? Or are those two different crashes that are triggered by > different situations? The different descriptions posted previously were due to the fact that I am running multiple MacPorts installations here on my machine. One uses a debug version of QT and KDE and another one doesn't use any debug versions. The backtrace from the latter one is shown above. And that's also the one we should focus on for now, I guess. As I said above, I haven't figured out yet how to reliably make sure that ONLY debug libraries are used in an application. Once I've found the proper way to achieve this, I could go further. I'll be on holiday next week, but I'll keep in touch with you afterwards, since this bug has been annoying me since quite a while. :-)
For completeness here once again the link to my little demonstrator app: https://bitbucket.org/mkae/kde-tests/src/9b358fdbe20f/AboutBoxCrash/ being derived from tutorial2 originating from http://techbase.kde.org/Development/Tutorials/Using_KXmlGuiWindow The crashing code can be download via: https://bitbucket.org/mkae/kde-tests/downloads
I did further experiments with my debug version, but it leads nowhere. I can't get a functioning debug version built. Wondering how we could tackle this problem. Looks like you could send me some patches for kdelibs4 which I'd incorporate in my installation, which then would allow to get more information about what's going on here.
I can't think of anything I can do from here, it's all a needle-in-a-haystack situation without a full backtrace.
OK, I see, so I guess I have to find a way to get a full backtrace from my demonstrator program...
Unfortunately I cannot build kdelibs4 as debug version without also building QT as its debug version. Doing the latter lets me end up with the dilemma that I have no chance so far to run any of my programs in their debug versions without immediate crashes. :-( I am off into holidays now. :-)
I can't really get an answer from neither QTdev nor QTbug about how to get a debuggable QT application up and running on MacOSX. So, I guess I won't be able for now to give you more readable information about what's going wrong here. Please, keep me updated about changes which might affect this issue.
The bug obviously also happens to exist on recent Linuxes: see https://bugs.kde.org/show_bug.cgi?id=278157 So, Teo, perhaps there's hope you'll get debug info from Jack. :-)) (I haven't been able to figure out how to deliver full debug info on MacOSX.) :-(

Thanks to Marko for pointing me to this bug. I have a problem with KMyMoney compiled from svn under ArchLinux with KDE 4.6.5. All the tabs in Help/About KDE work fine, but I get a crash in Help/About KMyMoney clicking on either the Authors or Thanks To tabs. Note that I do NOT get any such crash with KMyMoney 4.5.3 under Gentoo. Here's the backtrace: Application: KMyMoney (kmymoney), signal: Segmentation fault [KCrash Handler] #7 0xb59b83f8 in ??

Note I also get what seems to be the same crash from the Configure/Configure KMyMoney page in the Plugins section if I select the "i" for any of the plugins and then click the authors tab on the plugin's about dialog. Please let me know if there is anything else I can provide. (I do not currently have any other locally compiled KDE apps on this box, but I'll be glad to try one if it will help track this down. Jack
With KMyMoney 4.5.3 on kdelibs 4.6.5. and Archlinux it doesn't crash, but I can confirm your crash with the kmymoney-svn PKGBUILD. I'm still not sure it's exactly the same as the one first reported here.
In case it matters, I still get the crash on Archlinux with KDE 4.7.0 and KMM compiled from svn. Is there any other information I can provide or troubleshooting I can do?
I would appreciate if KMyMoney developers could please take another look at this, as it only seems to happen with a recent build of KMyMoney and nowhere else.
Teo, please see my comment #2 above, where I list links to test code. This all is not KMyMoney-specific, but it is caused by QT4/KDE4 at least on MacOSX. Unfortunately I am still unable to get a debug version built on it, here. Because of this it's interesting to see that Jack sees it also on Archlinux. I wonder whether he can give you more information. I'm interested myself as to what it is in his case. Hope he comes back with more info!
I'll contact Jack whether he can give my test code a try on his Archlinux.
I was referring to the other backtrace, it's different, at this point I wouldn't bet they are related at all.
Oh, I see, I am sorry then. PS: I figure you can build and run my "test code" just fine on your Linuxes...
(In reply to comment #16) > I'll contact Jack whether he can give my test code a try on his Archlinux. Unfortunately (?) that test code compiles and runs without crash on both Archlinux with KDE 4.7.0 and on Gentoo with KDE 4.6.3. However - I just tried compiling svn on my Gentoo box, and I DO get the crash there, but not with 4.5.3. (This is running .../build/kmymoney/kmymoney without doing make install.) Unfortunately, this does seem to point to KMM rather than KDE. I hate to ask whether a svn bisect approach might be worth the effort to find exactly what commit created the problem? Marko - do you know the oldest version of the code (svn commit, perhaps) that showed the problem, so I can try that exact version?
(In reply to comment #19) > Unfortunately (?) that test code compiles and runs without crash on both > Archlinux with KDE 4.7.0 and on Gentoo with KDE 4.6.3. Well, Jack, that's all consistent then. As Teo pointed out the crash trace points that already out. > without doing make install.) Unfortunately, this does seem to point to KMM > rather than KDE. Yeah, it seems that it's KMM's problem then. > Marko - do you know the oldest version of the code (svn commit, perhaps) that > showed the problem, so I can try that exact version? What code are you talking about her? If we are talking about KMM then it is still happening, like the test code, which you just tried.
Well, it does look like we have two different crashes. Perhaps 278157 is not really a duplicate of this? Current status: On both Gentoo with KDE 4.6.3 and Archlinux with KDE 4.7.0, KMM compiled from svn crashes, but KMM 4.5.3 compiled from tarball does not crash. Marko's test program also does not crash. However, Marko does not get the crash with KMM compiled from svn in a virtual environment with OpenSuse and KDE 4.3.5. In addition, I just tested in a virtual environment with Kubuntu and KDE 4.5.5 and KMM compiled from svn does not crash there either. Is it possible something that changed in KMM after 4.5.3 interacts with something that changed in KDE since 4.5.5 to cause the crash?
I could verify that my test application on my virtual OpenSUSE 11.4 ran through the about dialog WITHOUT CRASHING with KDE 4.6.0 installed.
I can also verify that the test application runs without crash on a vm with OpenSUSE 12.1rc3 with KDE 4.6.5...
Additionally I can finally say that KMyMoney's latest svn version could be built and run on said OpenSUSE 12.1rc3 vm WITH THE CRASH described by Jack when entering the About dialog boxes tabs. This means we have to have to separate tickets for this, i.e. Jack's original ticket isn't just a duplicate of this MacOSX-specific ticket. Summary: Crash in Author tab of About dialog with latest KMM on KDE 4.6.5!
Created attachment 62475 [details] New crash information added by DrKonqi kmymoney (4.5.96-svn1241546) on KDE Platform 4.7.40 (4.7.40 (KDE 4.8 >= 200110623) using Qt 4.7.1 From the stack trace it is clear that the code from KAboutApplicationPersonListDelegate::paint style->drawPrimitive(QStyle::PE_Widget, &option, painter, 0); causes a crash in Qt when a custom stylesheet is used by the application. This is because in static QWidget *containerWidget(const QWidget *w) from qstylesheetstyle.cpp w is used without checking if it's 0. Although this is Qt's fault not KDE's. -- Backtrace (Reduced): #6 0x00007f6002a931c8 in QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData> >::operator-> (this=0x8) at /home/kde-devel/qt4/include/QtCore/qscopedpointer.h:112 #7 0x00007f6002a92f96 in QObject::parent (this=0x0) at /home/kde-devel/qt4/include/QtCore/qobject.h:250 #8 0x00007f6002aa7e76 in QWidget::parentWidget (this=0x0) at /home/kde-devel/qt4/include/QtGui/qwidget.h:1022 #9 0x00007f6002ee78e8 in containerWidget (w=0x0) at /home/kde-devel/kdesrc/qt-copy/src/gui/styles/qstylesheetstyle.cpp:2380 #10 0x00007f6002ef5e68 in QStyleSheetStyle::drawPrimitive (this=0xd8e470, pe=QStyle::PE_Widget, opt=0x7fff605e8a70, p=0x7fff605e8c00, w=0x0) at /home/kde-devel/kdesrc/qt-copy/src/gui/styles/qstylesheetstyle.cpp:4252
I have just verified that the little test app crashes with a custom style. Shall I post this to QTdev?
Marko, could you please pursue this whit the Qt developers? From my point of view the BUG is pretty clear and with the stack trace I've just attached plus the explanation they can fix the bug without much effort. Thanks for all your perseverance with this!
Yep, I'll go for it then! Thanks for your endurance as well, Cristian! :-)

There we are: https://bugreports.qt.nokia.com/browse/QTBUG-19872 More I can't do for now. We'll see whether QTdev or QTbug are going to respond...
The upstream bug that was causing this https://bugreports.qt.nokia.com/browse/QTBUG-15910 was fixed in http://qt.gitorious.org/qt/qt/commit/0bf70c35bd51be4435c95f28dab96bf9f00b49db
*** Bug 281072 has been marked as a duplicate of this bug. ***
I just build QT4.7.4 on my MacOSX and I have to say that the bug still persists. Although the app doesn't crash immediately after clicking on the Authors tab it does when leaving the dialog by clicking the Close button.
Marko - since you built from source, can you confirm that the patch to git mentioned in comment #32 has actually been applied in 4.7.4? If not, we wait another round. If so, it might be appropriate to reopen your qt bug. (Archlinux is still on 4.7.3, so I still can't test yet.) Also - can you tell from the backtrace if it's really the same bug?
Yes, the backtrace looks like the one above: --- Program received signal EXC_BAD_ACCESS, Could not access memory. Reason: KERN_INVALID_ADDRESS at address: 0x0000000000000028 0x0000000100bdc1e8 in QObject::metaObject () (gdb) bt f #0 0x0000000100bdc1e8 in QObject::metaObject () No symbol table info available. #1 0x0000000100bdf737 in QObject::disconnect () No symbol table info available. #2 0x000000010011e0a8 in KWidgetItemDelegatePrivate::eventFilter () --- What concerns comment #32, you are right, it was a good idea to check that, indeed. The check for a NULL pointer is not yet present in 4.7.4. Thanks for pointing this our, Jack!!! So, I guess, we have to wait for 4.7.5 or something later.
