Es ist absolut untragbar, dass für die Identifizierung von Exceptions hier $e->getMessage() verwendet wird.

1.) Das Skript funktioniert dann ausnahmslos in einer deutschen Umgebung, die oft nicht gegeben ist
2.) Bei Updates des Zend-FW könnten sich die Fehlermeldungen ändern und das Skript würde nicht mehr funktionieren
3.) Wenn der Dateiname beispielsweise Umlaute enthält kommt es automatisch zu Problemen zwischen den verschiedenen Charsets (Linux verwendet UTF-8, Windows Wide-Strings bzw. UCS-2)

I was just testing out the Pdf demo in the demos folder and ran against this error:

Fatal error: Class 'Zend_Pdf_Resource_GraphicsState' not found in /opt/local/ZendFramework-1.11.11/library/Zend/Pdf/Canvas/Abstract.php on line 366

This was very odd, as all the files are there. Why is this coming up with just the basic demos?
