And here we go! My fault, didn't checked on project' site if it were a newer
version :-P
I donwloaded and compiled lightspark 0.7.2 (trisquel repository has 0.5.5)
and magically these f... bad player started to play! It works a little bit
slowly than adobe, but don't care. I can uninstall adobe-trash from debian to
make it full-libre again, and stay to trisquel with no problems. I will check
for an ubuntu-ppa for lightspark, to update it easily.
And so once again, my vrms will tell me that "rms would be proud" :-P
