Hi Johannes,

Thank-you for the help !!!
I was beeing crazy with this very-strange problem...

I have take few hours yesterday to test & test again this.

My last test was to change my kernel version (downgrade it from 3.6.11
to 3.5.7) & it's seem's i don't have anymore this problem.

I don't have the debugging symbols available for this package but if the
problem come back again (i don't think) i will install it from git to
have all debug information.

Thank you again for your time & disponibility, the community of
darktable is realy great!


Bye
