I hope that you have spelt that name right in the actual patch, because in 
this email, you didn't. It's "violoncelle.mov". this is french spelling 
for "cello".

Nearly every error message of GridFlow is turned into a crash in 
__cxa_allocate_exception because of the ATI/C++ driver conflict. There 
might be a GDB command that can show the contents of the error message in 
such a case, but i don't recall how...

I can't test the ATI/C++ driver conflict because I don't have access to 
such a computer these days.

AFAIK, the ATI driver problem occurs regardless of the distro. Perhaps 
someone can tell whether there is an alternate ATI driver from a different 
author, or any history of which versions have this conflict...
