Build ID: I20090611-1540

Steps To Reproduce:
1.open the attached "test.geo" file on eclipse 3.5 with GEF installed

2.open the outline view and error log view

3.change outline size to decrease its height to almost zero.
(see attached  pictures outline1.gif and outline2.gif)

4.error will throw in error log view. (see attched figure "error.gif")

More information:
1. this may be a corner case for most gef application. But it's common for our gef tool to have very big gef canvas with more than 100000 nodes. 
 
2. also appeared on eclipse 3.3.2 with  gef installed. both on linux platform.

3. the big rectange can not show correctly , this is another bug :
https://bugs.eclipse.org/bugs/show_bug.cgi?id=146179. This bug is not related to that one.
