[Evolution] Bug#637216: evolution-rss: Evolution consumes 100% CPU when I refresh RSS feed

[Pawel Tecza]

Package: evolution-rss
Version: 0.2.4~20110217-3
Severity: important

Hello,

I have a strange problem with one of my subscribed RSS 2.0 feed.
When I try to refresh it, then my Evolution starts to consume 100% CPU
and I have to kill it, because it's unusable.

Of course, I can download the feed manually using wget utility:

$ LANG=C wget http://webhosting.pl/feed/rss/all -O webhosting.pl.xml
--2011-08-09 16:01:20--  http://webhosting.pl/feed/rss/all

It seems that the file is OK:

$ xmllint --noout webhosting.pl.xml
$ echo $?

I've used strace tool to debug the problem. Below you can see a several
its output lines. Unfortunately I don't know how to understand it...

Any idea what's wrong?
