Summary: linux only? segmentation fault

Initial Comment:
This patch causes pd and pd-extended to crash, when opened and closed a number of times. Resulting message in terminal is: segmentation fault. A canvas object inside an abstraction with "graph on parent", which in turn is inside an abstraction with "graph on parent".
The same result when replacing the canvas object with a graphical bang.
Tested on Ubuntu Lucid, without desktop effects.
No crash on Windows Vista.

Message:
ah yes, I see it.  it happens between 3-5 cycles of opening and closing it
to trigger the crash, but sometimes it doesn't crash after 20 cycles.

I added this bug. It crashes for me on Ubuntu Lucid amd64, and i had the
same crash on Karmic intel 32.
You need to open/close the patch several times. The crash happens when
closing the patch for nth time.
