--- Comment #12 from Mike Kaganski <mikekaganski at hotmail.com> ---
The problem is that chart::InternalDataProvider does not implement
css::beans::XPropertySet, which makes PropertyHandler::inspect (called from
DataProviderHandler::inspect) to assign nullptr to the m_xComponent, and then
dereferencing it inside DataProviderHandler::getPropertyValue segfaults.

The code in FormComponentPropertyHandler methods (e.g.,
impl_getPropertyValue_throw) seems to dereference m_xComponent unconditionally
- that seems odd. But I have no idea which should be the fix - if the interface
is needed (and then it should throw when the interface is null) or the
dereference should be guarded by checks (because it may be null for a good
reason) (and I am not working on this - just placing it here for whoever has
the idea).
