[imp] Can't display HTML mail, blank page

[MrJacK]

Hi,

I have a current CVS version of horde/imp. And my problem is the
following, when i set the html driver in mime_drivers.php
($mime_drivers['imp']['html']['inline'] = true;) if i try to display an
email in HTML format i just get a blank page. I don't understand if i
have forget something or if it's just a bug but i don't think because i
can't find anything on the maling list about this problem.
Thanks in advance for your help.
