Bug when i create discussion

We're investigating, thanks !
Edit: What did you try to do exactly to make it crash ?

I posted a message and the code that i have put as an external link (contain japaneese character that could maybe be the source of the pb). When i clicked "create discussion", nothing happened on screen. So i have try to clic on "create discussion". Nothing happen. So i have supposed there was a problem with my windows / discussion. I have go again on discussion screen and seen my 2 last creations try. I have try to clic on them and i returned on Gamebuino Welcome page. I have try to create new discussion. I have paste the texte of the message and inserted a multiline code zone. I have paste the code. Next, i have try to validate the creation. Nothing happened. So i have supposed it was same. I have returned on discussion screen. I have try and had same effect, so i posted the request to delete these 3 unusables posts. After, as i supposed it's had a rapport with the japaneese characters, i have make a try with a text and a n external link and discussion has well been created. So i think that something in the text of the source make the procedure of validation of an discussion crashed but it's write nothing and discussion is created but with a special effect as it's open the welcome page.

Thanks, the Japanese characters crash the search engine we use apparently :(
