Today's calligrasheets crashes

Fri Nov 30 11:00:28 GMT 2012

Hi everybody,

Ok, so this issue was a mixture of my own confusion with an already
installed Calligra and the fact that the code that uses Calligra that
I'm working on was not yet setting Part to Doc. In a private mail
Boudewijn hinted me to do this.

    Part *part = new Part(0);
    Doc *doc = new Doc(part);
    part->setDocument(doc);

And now it works.

Unfortunately isn't Part.h of sheets/part being installed at this
moment. So I'll provide a patch to add it to the install files in a
minute.

Kind regards, and thanks Boudewijn for the support

Philip
