When having the user specify a file name for download, Galeon doesn't check
whether the user actually has permissions to create and/or write to this file.

I tried downloading a file to a root-owned directory with 755 permissions
on an ext3 partition. Galeon downloaded the file to the /tmp directory,
then, after not being allowed to copy it to its destination, left it there
with its mangled name, without any notification to me, or a message to the
console.

On a side note, I also don't like the Internet Explorerish way of
downloading to /tmp first. I like it better if the actual file was
directly, progressively written, like wget does it, this would also assist
crash recovery and fix above bug as well. But perhaps that's just me.
