1) Can you get the same output via kcrash dialogue - it would be easier to see which thread caused the crash 2) Can you add the following into the activitymanager-pluginsrc, "Global" section disabledPlugins=org.kde.kactivitymanager.activityranking 3) Remove all previously installed kamd files and reinstall it. (In reply to comment #1) > 1) Can you get the same output via kcrash dialogue - it would be easier to > see which thread caused the crash Curiously enough, no thread is marked as [KCrash Handler] Application: KDE Activity Manager (kactivitymanagerd), signal: Segmentation fault: 11 [New Thread 80bc0f000 (LWP 100616)] [New Thread 80bc0e800 (LWP 100614)] [New Thread 80bc0d000 (LWP 100613)] [New Thread 80bc07400 (LWP 100362)] [Switching to Thread 80bc0e800 (LWP 100614)] 0x0000000802eec0e7 in ??

I'm now on v4.8.90-56-g7b4fe53 with the same entry in activitymanager-pluginsrc, but the plugin isn't ignored anymore, so kactivitymanagerd has started crashing again.

What happens in frame 15 (KPluginFactory::create<Plugin>) is that qobject_cast doesn't recognize an ActivityRankingPlugin object created by the code in DSO (activitymanager_plugin_activityranking.so) as a Plugin object. I am not sure if this problem is 100% FreeBSD-specific or if other platforms are affected too. Basically it seems like a variation of this more general C++ vs dlopen issue: http://gcc.gnu.org/faq.html#dso There is one instance of Plugin::staticMetatData in kactivitymanagerd executable and there are other instances of it in all the plugin .so files. When a .so is dlopen-ed the runtime linker does not merge these definitions/instances. So, the instances of Plugin subclasses instantiated in DSOs point to the local copy while qobject_cast compares (by pointer comparison) them with the "main" copy. This mismatch leads to inability to properly load any plugin and also to the above crash. I have not investigated the details of the crash, but I suspect that it is also caused by the same kind of a mismatch. Because the destructor does not seem to have any bugs and should properly work on a constructed object. Final note, I was able to work-around this issue by using the advice from the gcc faq to pass -Wl,-E linker flag. I am not why/how things work with that flag on other platforms or for other KDE / Qt programs that make use of plugins. Further info.
It looks like on Linux cmake would automatically add -rdynamic option when calling gcc as a linker.
-rdynamic translates to -export-dynamic linker option.
In my copy of cmake files cmake/Modules/Platform/Linux-GNU.cmake defines __linux_compiler_gnu macro:
macro(__linux_compiler_gnu lang)
# We pass this for historical reasons. Projects may have
# executables that use dlopen but do not set ENABLE_EXPORTS.
set(CMAKE_SHARED_LIBRARY_LINK_${lang}_FLAGS "-rdynamic")
endmacro()
and then cmake/Modules/Platform/Linux-GNU-CXX.cmake has:
include(Platform/Linux-GNU)
__linux_compiler_gnu(CXX)
This treatment is not applied to FreeBSD with GNU/GCC toolchain.
Perhaps a bug in cmake?
Could anyone please double-check with make VERBOSE=1 that -rdynamic is indeed used on Linux when linking kactivitymanagerd?
in any case, according to the above comment the following property should be a cross-platform solution:
http://www.cmake.org/cmake/help/v2.8.10/cmake.html#prop_tgt:ENABLE_EXPORTS
Also, perhaps it would make sense to amend the FreeBSD ports framework to set CMAKE_SHARED_LIBRARY_LINK_${lang}_FLAGS at least for Qt and KDE ports.

Whenever kactivitymanagerd is started (either manually via gdb, or when Dolphin is loaded, or when KDE starts), it crashes. I'm using both kactivities and nepomuk-core from the master branch (respectively at v4.8.90-39-g90c38c5 and v4.9.0-63-ga14b147).
