foreign distro: QT5 loads/searchs plugins from wrong location

[Hartmut Goebel]

Hi,

before fling a bug, I jsut want to know whether I missed some update:

I just packages a simple GUI application using pythonqt5 and
python-poppler-qt. When running it fails with:

    Could not load the Qt platform plugin "xcb" in "" even though it was
    found.

When running with QT_DEBUG_PLUGINS=1 it reveals the cause:

    QFactoryLoader::QFactoryLoader() checking directory path
    "/usr/lib64/qt5/plugins/platforms" ...
    QFactoryLoader::QFactoryLoader() looking at
    "/usr/lib64/qt5/plugins/platforms/KWinQpaPlugin.so"
    Found metadata in lib
    /usr/lib64/qt5/plugins/platforms/KWinQpaPlugin.so, metadata=
    [… many lines skipped …]

    Got keys from plugin meta data ("xcb")
    QFactoryLoader::QFactoryLoader() checking directory path
    "/gnu/store/608bvypsh90c58apvd2cgg3m9l2pwjqn-python-3.7.4/bin/platforms"
    ...
    Cannot load library /usr/lib64/qt5/plugins/platforms/libqxcb.so:
    (libQt5XcbQpa.so.5: cannot open shared object file: No such file or
    directory)
    QLibraryPrivate::loadPlugin failed on
    "/usr/lib64/qt5/plugins/platforms/libqxcb.so" : "Cannot load library
    /usr/lib64/qt5/plugins/platforms/libqxcb.so: (libQt5XcbQpa.so.5:
    cannot open shared object file: No such file or directory)"

Looks like the plugin is search in the wrong location and also the list
of plgins.
