the unstable ABI changed. did you recompile QtCurve after installing kde-workspace/kwin? *** Bug 301746 has been marked as a duplicate of this bug. *** might as well be caused similar to bug #301728, but NOTICE that the unstable deco ABI broke nevertheless - any deco inheriting the unstable deco MUST be recompiled, regardless of whether 301728 gets fixed or not. *** Bug 301994 has been marked as a duplicate of this bug. *** *** Bug 302029 has been marked as a duplicate of this bug. *** Git commit 7abe24039517e50dcda843beac2e5deff5a789b3 by Thomas Lübking.

No, I just downloaded new Kubuntu packages. And I removed from my system dekorator and crystal kwin packages, but then I saw that console output complains about every possible kwin decoration:oxygen, oxygen-transparent,keramik, qtcurve ... The konsole output is irrelevant, it's merely a warning for developers to start supporting the API version tag. > And I removed from my system dekorator the decoration "deKorator" [1] is what triggers this crash, it must still be installed. It's however not using the unstable API, so the last crash would be a dupe of bug #301728 It is not the same as "kde4-window-decorator" what is a compiz decorator on the kwin decoration API. Please to grep -iE '(mime|clientgroup)' /usr/lib/kde4/kwin3_deKorator.so and check whether there's match.

PS. all packages are up to date. Where do you get those packages? (In reply to comment #23) > Where do you get those packages? From "standart" Kubuntu Backports: http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu Package Details: http://img855.imageshack.us/img855/362/packagedetails.jpg I've downloaded the package and it does apparently not have "clientGroupItemDragMimeType" (unlike my version of the library) what (possibly) means https://projects.kde.org/projects/kde/kde-workspace/repository/revisions/412f28e5c88803109c56b8cbd923a69fc09bdfeb (ABI restorage) is not part of that library?! adding Jonathan to CC: please have a look starting from comment #21. There might be something wrong with your 4.9 packages GA-RUMPF! The absent "clientGroupItemDragMimeType" symbol is matter of stripped ./. not stripped. The reason is that I re-added it as "semi-inline (?)" header implementation (ie. just let it return tabDragMimeType) what is apparently not ABI stable.... Making it a nice clone of tabDragMimeType instead with accurate implementation in the sources leaves the symbol in the library. *** Bug 304407 has been marked as a duplicate of this bug. *** *** Bug 304581 has been marked as a duplicate of this bug. *** *** Bug 304584 has been marked as a duplicate of this bug. *** From the valgrind log in comment #17: ==16162== Invalid read of size 4 ==16162== at 0x112D79F4: KDecorationOptions::font(bool, bool) const (in /usr/lib/libkdecorations.so.4.8.0) ==16162== by 0x1133976C: create_factory (in /usr/lib/kde4/kwin3_smaragd.so) ==16162== by 0x10473F27: KDecorationPlugins::loadPlugin(QString) (kdecoration_plugins_p.cpp:241) ==16162== by 0xA61FB6F: ??? ==16162== Address 0x4 is not stack'd, malloc'd or (recently) free'd The last line indicates that the options pointer, or a pointer referenced internally be the options, is 0. So the regression is not an ABI change, but an internal change in KWin (some pointer isn't initialized correctly). I guess it has to do with the version checks, which would explain why it doesn't crash when recompiling.

Unlikely. The options are a global instance created as first element of the only m_preview object in the entire lifetime of the kcm and deleted last (with it) Also iirc, we got these crashes with kwin as well, where the options are the only and global kwin options. Nothing changed in that area at all (not to mention that with an invalid m_preview we'd get a crash before since we can't access any of the factory pointers) It's also not the factory pointers (this time) as smaragd crashes when creating one (since it has the first options pointer then, while decoraktor and skulpture access options when creating a decoration - in doubt in createMainWidget) Plus: this doesn't explain at all why it only happens for selected decorations and mystically vanishes with recompilation, because: > I guess it has to do with the version checks, No. > which would explain why it doesn't crash when recompiling. Just recompiling will not get you a matching API version - it needs to be exported in extern "C" KDE_EXPORT int decoration_version() Also for every decoration but the ones known to have used the unstable API, the version is just sanitized and the remaining codepath is the same (what is irrelevant, because just recompiling will still not change this at all) I don't know what causes those crashes. Removing and re-adding the mimetype symbol from libkdecoration did not crash any decoration here. Bug #304584 is on i686, all others on x64 Could be compiler options (-O3 magic, the only constant i see here is Ubuntu) - I don't know. It's however not by a difference in the runtime code after recompilation. If recompilation fixes the issue, it's likely rather relinking - and by this some ABI juggle. @Mirza: you'vve got a bunch of old decorations not shiped with kwin since ages here - can you check which package installed them? TIA... /usr/lib/kde4/kwin3_kde2.so /usr/lib/kde4/kwin3_keramik.so /usr/lib/kde4/kwin3_modernsys.so /usr/lib/kde4/kwin3_quartz.so /usr/lib/kde4/kwin3_redmond.so /usr/lib/kde4/kwin3_web.so (In reply to comment #34) > @Mirza: > > you'vve got a bunch of old decorations not shiped with kwin since ages here > - can you check which package installed them? > > TIA... > > /usr/lib/kde4/kwin3_kde2.so > /usr/lib/kde4/kwin3_keramik.so > /usr/lib/kde4/kwin3_modernsys.so > /usr/lib/kde4/kwin3_quartz.so > /usr/lib/kde4/kwin3_redmond.so > /usr/lib/kde4/kwin3_web.so They all come from: kdeartwork-theme-window I found that out by running: mirza@MirzaLaptop:~$ dlocate /usr/lib/kde4/kwin3_kde2.so kdeartwork-theme-window: /usr/lib/kde4/kwin3_kde2.so all styles contained int this package: /usr/lib/kde4/kwin3_kde2.so /usr/lib/kde4/kwin3_keramik.so /usr/lib/kde4/kwin3_modernsys.so /usr/lib/kde4/kwin3_quartz.so /usr/lib/kde4/kwin3_redmond.so /usr/lib/kde4/kwin3_web.so /usr/lib/kde4/kwin_kde2_config.so /usr/lib/kde4/kwin_keramik_config.so /usr/lib/kde4/kwin_modernsys_config.so /usr/lib/kde4/kwin_quartz_config.so Ok, thanks - those are new compilations as well what explains why they don't cause trouble. *** Bug 304610 has been marked as a duplicate of this bug. *** *** Bug 304638 has been marked as a duplicate of this bug. *** *** Bug 304645 has been marked as a duplicate of this bug. *** Tested the packages today on Kubuntu 12.04 and kcmshell4 kwindecoration loads without crashing with kdeartwork-theme-window installed, so I presume this is down to self compiled window decorations. The ABI version was changed in our packages in libkdecorations because there was an ABI compatibility. *** Bug 304662 has been marked as a duplicate of this bug. *** Jonathan, the problem is not "self" compiled, but "compiled using 4.8 headers". If the ABI version had changed, the old decorations would not load at all, because of a library missing. Instead, they simply crash when accessing options. And I am sure the package you tested was compiled against the 4.9 headers. Also, I'm quite sure that it's about some compiler option. Reason: i've a bunch of legacy decos installed. I compiled and added them after they got removed in 4.5 or so. I'm also pretty sure to never have cared much about them later on - and esp. not recompiled them ever. Nevertheless, none of those decos has *ever* crashed the kcm for me. For me the crashing ended after I removed Skulpture windeco package. So to me it seems like there's binary incompatibility that isn't taken care of with package dependencies? *** Bug 304766 has been marked as a duplicate of this bug. *** *** Bug 304949 has been marked as a duplicate of this bug. *** *** Bug 305124 has been marked as a duplicate of this bug. *** third party kwin-style packages recompiling now in the PPA to pick up the new ABI, sorry for the hassle thanks for taking care of it. I think from our side there is nothing we can do about this issue anymore, so I set to RESOLVED DOWNSTREAM. In future we will inform the packagers about ABI changes in libkdecoration and also tell them that there is no need to change the so number ;-) Jonathan, the message that KWin developers forgot to communicate downstream is: "There is no ABI change, despite it looking so", so I am not sure recompilation against "the new ABI" (which does not really exists) is the right solution. Maybe simply revert the ABI bump, so that old compiled code does not crash. KWin automatically rejects "unstable" decorations anyway, unless they provide new version information. *** Bug 305536 has been marked as a duplicate of this bug. *** *** Bug 307043 has been marked as a duplicate of this bug. *** *** Bug 307724 has been marked as a duplicate of this bug. *** *** Bug 326676 has been marked as a duplicate of this bug. *** (In reply to comment #54) > *** Bug 326676 has been marked as a duplicate of this bug. *** Thanks Thomas. I had to purge kwin-style-qtcurve and kde-style-qtcurve before systemsettings would let me into "Window Decorations" because qtcurve was evidently still referenced there until I removed all of it.. First I purged kwin-style-qtcurve and restarted X. The initial kwin crash went away and the desktop was back to normal. But, when I went to systemsettings/Window Decorations, systemsettings would always crash. Then I purged kde-style-qtcurve and I can once again use systemsettings without a crash. It's a pity, I really like qtcurve, but it has caused me trouble before too. I guess I don't like it that much after all. (In reply to comment #55) > It's a pity, I really like qtcurve, but it has caused me trouble before too. > I guess I don't like it that much after all. NOTICE that QtCurve itself is NOT broken. This is just an issue with binary compatibility, ie. the compiled binary for QtCurve does not match the compiled binary for kwin. -> Just ask your distro for a clean/updated package or compile it yourself.

Ups, sorry for this attachments. I wasn't carefull I didn't noticed that it is resolved downstream. But I reported bug for Kubuntu: https://bugs.launchpad.net/ubuntu/+bug/1377051 crashes 1&2 happen for the smaragd decoration. notice, that the bug is NOT in smaragd, this happens for the downstream symbol relocation. uninstall or update ALL 3rd party decoration plugins. crash 3 is entirely different and caused by a python plasmoid, likely ultimately caused by pykde and/or pyqt binary inpompatibilities (but i lack expertise in this context) Thank you very much for your help, Thomas. Your diagnosis was right. I had to uninstall smaragd and it works. Sorry for trouble. |
