[Piwik 2.1.0] TCPDF V6.0.044 - Logo on PDF Report :S

Hi,

After updating to the latest version, the logo on the first page of the PDF report still does not show.
Although other images are still showing on the report except for the logo. See attached image.

We initially used the default Piwik logo but it does not show.
We changed the logo to our own by uploading a JPG image but still the same.

We disabled other themes and only used Zeitgeist.

Our web server is lighttpd and running PHP v5.5.3.

Please help!!!

Thanks.
