Duplicate of bug 270679 (or bug 270312)?

testing with firefox 1.0.7

I don't believe that this is related to bug #270312 because it still happened after clicking cleanup in download manager or manually deleting downloads.rdf.  It may very well be a dup of bug #270679. I didn't include expired bugs in my search.  Interestingly, ftp://mirrors.kernel.org/gnu/aspell/aspell-0.50.4.1.tar.gz no longer reports file size unknown.
