Comment 1 Camilla Boemann 2012-06-10 12:26:08 UTC

I can confirm. it crashes when inserting a textshape (even the first one, but i'm using a template so there is already a textshape we insert on top of i guees)

Thanks. Will look in to it now

Comment 2 Camilla Boemann 2012-06-10 12:38:30 UTC

It's 87dd80da75f5b2425ff8f04954a87650cb7be790 that causes it.

I'll figure out why and fix

If inserting a textshape, the qtextdocument is now modified which made a rootarea to be created
We need to explicitly set the root area to 0 whenever setting the document. Even if it's the same
document.
