This has nothing to do with zanshin per se, but while running the tests I noticed the following log message which I've never managed to link to a specific source code issue :

```
Aug 27 22:41:15 Portia.local akonaditaskqueriestest[24501]: dynamic_cast error 2: One or more of the following type_info's  has hidden visibility.  They should all have public visibility.   N7Akonadi11PayloadBaseE, N7Akonadi7PayloadI14QSharedPointerIN8KCalCore9IncidenceEEEE, N7Akonadi7PayloadI14QSharedPointerIN8KCalCore9IncidenceEEEE.
```

the symbols are, in order : `Akonadi::PayloadBase` , `Akonadi::Payload<QSharedPointer<KCalCore::Incidence> >` (2x) 

if you (or someone else) has any idea about a possible solution ... rebuilding without `-fvisibility=hidden` didn't help in any case.
