Comment 11 for bug 137773

You can quickly fix this error:

*** unhandled exception in callback:
*** Can't call method "get_url" without a package or object reference at /usr/share/yarssr/Yarssr/Feed.pm line 158.
*** ignoring at /usr/share/yarssr/Yarssr/GUI.pm line 115.

by the following:

sudo gedit (or whatever program you want to use) /usr/share/yarssr/Yarssr/Feed.pm
insert a line before line 158 with: if ($item) {
insert a line after line 162 with: }
save the file

This will allow you to start yarssr and get rid of the faulty feed.

(I'm not marking this as a patch as I'm thinking it probably doesn't solve the issue, just a quick fix to get it up and running ftm)
