Irregular gtk application behavior - Help

[Ariel Fritz <duin tutopia com>]

Hi all

Im testing the follwing code and I have some problems. I want to emulate 
a temporized label. When the application start I want to show the label 
and after x time (here 2 sec) I want to destroy it.
When I run the applictation sometimes the label isn't shown but 
sometimes it's shown well.
What's wrong? Any Idea? How can I solve this problem? What do I have to 
change in the code to emulate this? Any suggestion?

Thank a lot

Ariel
