Description Leon Stringer 2008-04-19 12:52:13 UTC

Steps to reproduce:
1. Create new diagram.
2. In the toolbox click 'Box' and click on the diagram window to add it.
3. In the toolbox click 'Text' and click on the diagram window to add it.
4. Type some text for the newly added Text (e.g. "Test").
5. Drag the Text object so that the green connection point is over the centre of the Box object so the point turns red to indicate it is linked.
6. Save diagram and close diagram window.
7. Load diagram (e.g. from the toolbox File menu). Dia crashes.

thanks for the debug help, just fixed :

2008-04-19  Hans Breuer  <hans@breuer.org>

	* objects/standard/textobj.c(textobj_load) : intialize TextObj::attrs 
	from TextObj::text (bug #528903, Leon Stringer)
	* objects/Istar/goal.c objects/Istar/other.c objects/Jackson/domain.c
	  objects/SADT/box.c : had a similar problem leaving attrs 
	 uninitialized in their create method
