Konqueror log
It is crashing only when I'll try to open context menu on files, it works correctly with directories. Pawel, on your system is a "kdeconnectfiletiemaction.so" plugin installed, which is linked to Qt5. Dolphin and Konqueror, however, are linked to Qt4. For now, I suggest to downgrade to the KDE 4 version of kdeconnect. I am completely unsure who needs to ensure mixed versions are not allowed in the plugins. It could be a Dolphin issue, or some KService issue. Reassigning to Dolphin developers for now. Albert, please note the wrong .so name, it should be "kdeconnectfileitemaction.so" Christoph, I've upgraded to KDE 5 in order to catch & report bugs and won't downgrade :) Dolphin 4 shouldn't be loading the KDE Connect 5 plugin. It looks like a problem in the path where KDE Connect is installed (it looks like you compiled it manually, so maybe some CMake option caused this) and/or with how Dolphin handles the plugins. I'm actually using packages from here: http://taper.alienbase.nl/mirrors/alien-kde/current/testing/ and as advised I've uninstalled whole KDE4 packages installed previously. You haven't uninstalled KDE 4 completely, because the version of Konqueror and Dolphin you have are from KDE 4. This is how Dolphin and other applications get the context menu plugins: const KService::List pluginServices = KMimeTypeTrader::self()->query(commonMimeType, "KFileItemAction/Plugin", "exist Library"); I don't see any way how one could tell the "query" function about the version, so this looks like a KService issue from my point of view. (And it's probably better to implement this version check in KService than in every application that uses it - KService should know if it's the Qt4 or the Qt5 version after all). I'll reassign to the KService framework, but actually, it would be desirable to have this fixed in kdelibs 4.x too. Well you can extend the constraint to say something like
and [X-KF-Version]=5
and add X-KF-Version=5 to the plugin desktop files.
Alternatively (probably better), the plugins should use just json (no desktop file) and the kf5 based dolphin should use KPluginLoader to load these plugins (from a specific subfolder of the plugins dir, no trader query needed). Qt's builtin version check will then take care of the qt5 vs qt6 issue next time :)

Created attachment 91262 [details] Dolphin log Happens both in Dolphin (version 14.11.97) and Konqueror (KDE 4.14.5). When in file manager I'll right-click on any file, applications are crashing. Attaching GDB logs for both applications
