[SOLVED] When script crashes: Traceback appears only AFTER Blender closes

Hi,
I’m confused by the way my version of Blender reports errors.
If a script is working well, the console is well informative with :

Blender Game Engine Started
Blender Game Engine Finished

But, if for example, I introduced a little error (like an unknown variable for example), I’ve got this:

Python script error - object 'Cube', controller 'Python':

And… that’s all. Even if there is a colon at the end of the sentence, I’ve got no detailed infos after that. it looks to me as if my traceback is always cut before the end.
It’s only when I close completely Blender that the complete traceback appears.
Is there an option in Blender to activate the traceback or something to have that without having to close Blender??

Another thing :
When I run a simple script (not from the blender game egine): if there is an error, blender shows a window: “The script fails: look inside the console for now…”
But when I look inside the console there is only:

Error: Python script fail, look in the console for now...

And then, it’s only when I close Blender that the complete message error appears with the error and the line number.
It’s a bit strange to have to close Blender each time to get my error??

My settings:
Blender 2.66a
Lubuntu 3.10

Thanks a lot in advance

Ooh got it! I run Blender by “gksudo”. Apparently it doesn’t work with that. Sorry for the neebie discovery…
