Bug Description

When downloading a file in Epiphany which does not have a total size reported (the download window says 'Unknown' in the progress box), a huge amount of CPU time is used by the download compared to downloading a file with a known download size. There doesn't seem to be a need for this, and I don't think the problem exists in Firefox.

Example link: http://video.google.com/videoplay?docid=8723130163011577496&q=red+vs+blue+02 -- then click on 'Download' to the right. Downloading this file, or any other from Google Video, gives me the same problem.

Thanks for the report

What version of the epiphany-browser package do you have installed? Do you still have this issue?

If so, what sort of difference in CPU utilisation is there?

I will test this soon (I'm currently booted in to Breezy). I have seen the problem recently, but I have not tested it with the latest Epiphany version in Dapper.

When the problem occurs though, the CPU usage goes to ~100% for the duration of the download even with nothing else running in the background, and CPU usage drops back down to normal (0-3%) after the download completes.

I just tested this with the latest Dapper updates, and Epiphany does still do this.

According to top, during the download epiphany is using ~70% of the CPU while xorg is using ~24.2%. When idle, these don't even show up on the list, or stay below a few percent.

If I have further comments, should I post them here or to the Gnome bugzilla?

It would probably be best to post them to the GNOME Bugzilla.

The bug has been fixed upstream

The patch is trivial: http://cvs.gnome.org/viewcvs/epiphany/embed/mozilla/MozDownload.cpp?r1=1.78.2.3&r2=1.78.2.4&makepatch=1&diff_format=u

I'll probably backport that fix to dapper-updates too
