Tabulator spaces are not shown in preview of tasks

Thanks for your bug. What version of Ubuntu do you use? Could you make a screenshot or attach an example of the issue? Is that an html or a text email?

As you can see here, the edit window correctly shows tabulator spaces in the edit box.

As you can see here the preview box (bottom, right box) does not show the tabulator spaces. They are simply ignored (second line) or replaced by normal spaces (line with letters).

This screenshots are taken from today's evolution version shipped with Ubuntu Dapper Beta.

It does the same here, I've forwarded the issue upstream: http://bugzilla.gnome.org/show_bug.cgi?id=340267
