You are obviously right. I always used g_free() to free errors, my fault.
I've grepped tons of sources and I had everywhere the code bugged, then I
googled around to search some more examples and I've found there are a lot
of other sources in the net where a GError is freed with g_free, I think
improving the documentation of the functions that use a GError as input
parameter may help programmers do not write wrong code in this situation.
