Thanks for the report, also reported in forum: http://forum.piwik.org/read.php?2,108609

[mattab]

I cannot reproduce the issue... If you also experience this problem, please post a comment. What PHP version do you use? Have you tried chmod 777 the directory piwik/tmp/tcpdf/ ?

[anonymous-matomo-user]

Same problem here (piwik v2.0.2). The Problem does not occur when selecting a date range within the current week/month. When choosing an older (archived?) date range, PDF generation fails and the following stack trace pops up:

/tmp/tcpdf permissions are rwx for the user running Piwik. PHP 5.3.8 on GNU/Linux.

Just noticed that when setting 'log_only_when_debug_parameter = 1' in config, the problem goes away.
