[Pkg-dia-team] Bug#534481: Bug#534481: dia 0.97-2 eats up all system memory

[Antonio Trueba]

Hi Roland,

Tested with several objects at random, the problem seems to be zooming while
antialias feature is enabled. Try the following:

- Start with a blank canvas (my default here is A3 size, guess the problem
isn't related to this)
- Add a "regval" object from "chemeng" sheet.
- Zoom in & out, resize or move at random, the memory usage should stay
moreless stable (~30MB here).
- Enable antialias
- Zoom in & out to random scales, the memory usage starts increasing
(~35MB).
- Resize the object to a big scale, say half the canvas' paper size.
- Zoom at random again, the memory usage grows faster this time.

Performing as above with just one object may not eat up memory too fast, but
drawing three of four simple objects speeds things way up. Also, I found no
differences while playing with the object's properties, nor when playing as
above without antialias feature.

Also, if you close the diagram but keep dia's toolbar open the memory is not
freed.

Hope this helps.
