[support] pdftotext throws tag errors

I am using swish-e indexer to index all PDF documents. The module works fine.

The problem is that one of the required binary file "pdftotext" throws errors:

/path/to/files/document.pdf:287: error: Tag srccontent invalid

dstport>143</commondstport> <srccontent offset="0" depth="128" ignorecase="true"

^

/path/to/files/document.pdf:287: error: Tag dstcontent invalid

epth="128" ignorecase="true">LOGIN</srccontent> <dstcontent offset="0" depth="5"

^

/path/to/files/document.pdf:287: error: Tag weight invalid

e">LOGIN</srccontent> <dstcontent offset="0" depth="5">* OK</dstcontent> <weight

it caused my server ran out of memory few times.

Have you guys seen anything like this?? Much appreciated any inputs
