[Orgmode] Missing line breaks in ps export of agenda

[Julia Jacobson]

Hello everybody out there using Org-mode,

The export of an agenda to a Postscript file doesn't seem break lines.
Whenever an item in my agenda is very long, it's just cut off at the 
border of the Postscript page.
Could anyone help me to make the whole line become readable by inserting 
a line break?

Thanks in advance,
Julia
