Comment 2 for bug 518341

supplement/correction:
I was wrong stating that I downloaded the file which made bzr crash -- correct is that the filename was generated automatically when I dropped the download location from firefox to the Gnome desktop, and copying that later into the archive tree to document where the file is from. I suppose that firefox deduced the strange filename from the html title of the download page, but anyway: bzr should be able to handle this (as git did).
