I cannot reproduce it in 0.96-pre5.  What version of Dia are you using?  Does it happen consistently?

Comment 2 jddcef 2007-03-05 13:13:36 UTC

Hi, Sorry about the poor description. I didn't think the bug report would actually go so far, onto this site :)

I just tested it again, and I can reproduce it.

1) New empty diagram. (it doesn't have to be empty)
2) Select flowchart from dropdown in left float bar.
3) Select a circle connecter (or any shape in fact)
4) Draw a circle while holding left SHIFT in. (But don't UNSELECT in the drawing area the circle) (This also crashes if you don't hold shift in this step)
5) Undo. (Ctrl-Z with the drawing window in focus)
6) Select another shape and draw holding SHIFT in. It will crash now. (holding shift in seems to be important here)

It doesn't happen if you unselect the shape before UNDO'ing. (Seems to be when you UNDO, but an item is still selected)
Seems to only happen with flowchart? (Haven't tested many others though)


OK, now with this information it can be fixed :)


Sincerely,

David

Thank you for the precise description.  Now I have it reproduced under Linux in 0.96-pre6.  Seems to happen with a variety of objects, not just from Flowchart - Misc/File also does this.  I suspect that the focus object points at the object that has disappeaed in undo.

Comment 5 Lars Clausen 2007-03-11 08:14:27 UTC

...and I was right.  It is fixed as of todays SVN and the upcoming pre7.
