Not again? KF5 - undefined symbol: _ZTV12MyMoneyMoney

[aga]

Now I'm getting -
"kf5.kio.core: Refilling KProtocolInfoFactory cache in the hope to find ""
KMyMoneyPlugin::PluginLoader:: createInstanceFromService returned
nullptr for Weboob with error Cannot load library
/usr/lib/x86_64-linux-gnu/qt5/plugins/kmm_weboob.so:

(/usr/lib/x86_64-linux-gnu/qt5/plugins/kmm_csvimport.so: undefined
symbol: _ZTV12MyMoneyMoney)...etc" when trying to run KMM.

I've deinstalled and reinstalled and confirmed that the distro package
is not installed.

What else can I do please?
