SUMMARY If I try to e.g. save page with too long file name, it is reported as ok, but file is not at its place. In download manager - its status is "canceled". Reported to gentoo before: https://bugs.gentoo.org/705692 Steps to Reproduce: 1. Open some page and try to save it 2. Manually enter name, that is known to be too long for given dir/fs. Actual Results: File is missing, and item in download list is "canceled". Expected Results: It could at least report about calcel reason. But don't report it as success. When I did so in Epiphany (gnome-web,gtk3), it clearly refused to save right in save dialog (could be gtk feature).
