I'm not sure why it says I'm using KDE KDE 3.5.5, or Mandrake RPMs, but I'm on
KDE 3.5.5 and Gentoo, if someone wants to edit the original report to make it
easier to find.

in kspread_object.cc it asserts at;
KoChart::Part* EmbeddedChart::chart()
{
    assert( m_embeddedObject->document()->inherits( "KoChart::Part" ) );
    return static_cast<KoChart::Part *>( m_embeddedObject->document() );
}
m_embeddedObject->document()->metaObject()->className() is kunavailpart...

OK, I see which recent change broke this, I'll add a fix.

Don't crash when the chart couldn't be loaded and we get KoUnavailPart instead.

 /**********************************************************

OK, crash is gone, but of course the chart loading still fails. Will reassign
to kchart.

David: Is the same fix applicable to kchart 2.0 as well?

I'll take care of the actual loading, but if something is wrong in the file, we don't want a crash.

Inge: I don't understand your question. Do you mean "to kspread 2.0"? I
forwarded ported the crash-fix iirc.

Yes, I meant kspread 2.0. And thanks for forward porting.

duplicate of bug #32405 ?

Let's mark it as duplicate since the crasher was fixed and the remaining wish
about a scatter-chart is just a duplicate of bug #32405 which has btw already
>=125 votes.
