The new version doesn't support PDF metadata as it should. The former version (exactly, *yesterday* version ;) would extract nicely the author, subject, keywords, and so on. No it can do only this:
bies@quine:~/Opole$ extract Dziobak.pdf
software - This is pdfeTeX, Version 3.141592-1.21a-2.2 (Web2C 7.5.4) kpathsea version 3.5.4
creation date - 20060528155926+02'00'
format - PDF 1,0
mimetype - application/pdf
At first I thought this was a feature;), but I checked also with the BibTeX option:
bies@quine:~/Opole$ extract -b Dziobak.pdf
% BiBTeX file
@misc{ thisdziob,
title = "Dziobak.pdf",
year = "This",
month = " i"
}
That means that the program now fails to recognize any data apart from the creation date and format...
The file itself isn't broken, because when I use pdftk everything seem to work fine:
bies@quine:~/Opole$ pdftk Dziobak.pdf dump_data

I suspect that the extract has a rigid idea of what data should be in what place, and when finds something is different, it brokes. For example, is seems to find PTEX.Fullbanner in the place it expects year and month...
I think I am able to get hte meta data properly.
>>extract output.pdf
modification date - D:20080714110537
creation date - 20080714110537

I am using following versions to test this.

Please provide the actual pdf and, the output and the version for all commands if this problem is still there.
