[IGSTK-Users] Segmentation Fault when Adding and Removing objects

[Vincent Gratsac]

Hi Matt,

Thank you for your fix.
I think that all is working fine now.

The only point I would like to underline is a mail sent on the 
igstk-developers mailing list by Torleif Sandnes (Nov 8th , 2007).
I'm actually facing to the same behavior and I can't see if Torleif 
found a solution to resolve this problem.
Could anyone give me some informations on this point ?

Thank you,

Vincent
