Description Hrvoje Senjan 2013-06-07 10:52:10 UTC 
Application: amarok (2.7-git)
KDE Platform Version: 4.10.60 "release 10"
Qt Version: 4.8.5
Operating System: Linux 3.10.0-rc4-1.gb3d0118-desktop x86_64
Distribution: "openSUSE 13.1 Milestone 1 (x86_64)"

-- Information about the crash:
- What I was doing when the application crashed:

*Probably* caused by fe61ba48d5bb86222684919fd27f339d0e7a1013 in kdelibs... as the bt shows it crashes in Plasma::Theme.
There is also a soprano/virtuoso related crash ...

The crash can be reproduced every time.

-- Backtrace:
Application: Amarok (amarok), signal: Segmentation fault

Comment 1 Jekyll Wu 2013-06-07 13:58:03 UTC 
I can confirm the crash. Rebuilding kdelibs from fe61ba48d5bb86222684919fd27f339d0e7a1013~ makes amarok work again for me. (Thanks for the hint).
Comment 2 Hrvoje Senjan 2013-06-09 18:34:31 UTC

Amarok workaround

I can open a review request/commit if this makes sense (for me it does, as the cause of the crash is that Amarok-Mockup theme doesn't exists anywhere)
But i don't know why it was used anyway/is there a (good) reason to keep it...

Remove usage of (fake) Amarok-Mockup theme

This is due to https://bugs.kde.org/show_bug.cgi?id=320855
Amarok-Mockup is unused, as far i can see, and also makes Amarok crash with kdelibs master/4.11
If it is still needed, or there is a better solution, i'll discard the review...

amarok (2.7-git) on KDE Platform 4.10.80 using Qt 4.8.4

- What I was doing when the application crashed:
Just tried starting Amarok. It did not open up and crashed after a moment.

Which exact git checkout do you use?
Comment 7 Emil Sedgh 2013-06-16 06:56:10 UTC 
Im on 876b34850 which does not include Mark's fix.
I think its safe to mark the bug as fixed.
Im having a hard time pulling the master due to weak internet connection.
I will reopen if I manage to get the master and see the problem persists.
Comment 8 Dominik Haumann 2013-07-09 20:44:54 UTC 
Are you sure this was an amarok issue?

I've upgraded to the kde 4.11 beta packages from openSUSE 12.3, and get a crash in KStandardDirs::saveLocation, KStandardDirs::locateLocal as well.

Affected are plasma, kmix, krunner. Maybe it's a broken installation, but I still wonder wheter this fix for Amarok is really necessary.

New crash information added by DrKonqi

kwin (4.10.90) on KDE Platform 4.10.90 using Qt 4.8.5

- What I was doing when the application crashed:

I was logging in. Similar crashes are seen with kwin, kmix and other KDE applications.

- Additional Information:

I have analyzed the crashed application in gdb, and I believe this code in Plasma::ThemePrivate::useCache() is the real culprit:

230             if (isRegularTheme) {
231                 const QString path = KStandardDirs::locate("data", "desktoptheme/" + themeName + "/metadata.desktop");
232                 const KPluginInfo pluginInfo(path);

Note that "path" is a relative path and KPluginInfo::KPluginInfo is called with only one argument. However, KPluginInfo constructor is declared as:

         * @param filename  The filename of the .desktop file.
         * @param resource  If filename is relative, you need to specify a resource type
         * (e.g. "service", "apps"... KStandardDirs). Otherwise,
         * resource isn't used.
         */
        explicit KPluginInfo( const QString & filename, const char* resource = 0 );

So, if you call it without the "resource" argument, the default value is used, which is NULL. This is invalid for a relative path, and indeed causes the crash further down the stack in KStandardDirs::saveLocation():

1499            if (dirs.isEmpty() && (
1500                    (strcmp(type, "socket") == 0) ||
1501                    (strcmp(type, "tmp") == 0) ||
1502                    (strcmp(type, "cache") == 0) ))

Unsurprisingly, calling strcmp(NULL, something) will cause a SIGSEGV.

proposed fix

This patch fixed the crashes for me. However, I'm not sure if "data" is the correct resource type here, so it should definitely be reviewed by someone who has a clue.
Comment 11 Gilboa Davara 2013-08-01 14:02:15 UTC 
FWIW the Amarok workaround patch seems to work just fine.
Fedora 19, x86_64,  KDE 4.10.97.

No, the path is not relative; it is empty. KStandradDirs::locate returns a full path .. unless it can't find what is being looked for.

So indeed, path needs to be checked for !isEmpty()
