It's because of the array notation. An array of pointers and a double
pointer (with a malloc) aren't the same.
Because it's a local variable in a function, the entire array is stored
on the stack, whereas with the pointer notation, only the value of the
pointer is stored. I bet "g_strfreev()" gives the error when it tries to
free mem from the stack.
So, to get rid of this, we could use something like this:
void ....{
gchar **argv = (gchar *) malloc(3 * sizeof(gchar *));
argv[0] = g_strdup(...);
argv[1] = ...;
argv[2] = NULL;
g_strfreev(argv);
}
