I apologize for my ignorance, just don't know how getting around.
I try but couldn't find the way to fix, so I decided to reinstall F15
for now it works OK, I also check the new installation with seahorse and
found to be exactly the same.
I would still like to understand the mechanism just in case that happens
again.
thank you very much.
