In general, when you use nepomukindexer with a file and that file is not located by nepoogle index process was failing.

As I wrote xmlindexer an rdfindexer are a good tools to try to detect problems.

I do a try with the pdf you attach to the bug report and is true that nepomukindexer has an error parsing the file but the file is indexed and is visible to nepoogle in my system.

On the other side, using pdftk-gui to fix the pdf file and after fix the pdf there is no error indexing the pdf.

In openSUSE this is the packages and versions I have installed:

• kdegraphics-strigi-analyzer - 4.8.0-24.1
• kdesdk4-strigi - 4.8.0-225.1
• libstrigi0 - 0.7.6-65.3
• libstrigi0-32bit - 0.7.6-65.3
• strigi - 0.7.6-65.3
• strigi-devel - 0.7.6-65.3

How do you recognize errors in xmlindexer and rdfindexer?
I don't see any obvious one.

In the file I uploaded in the bug page, I don't see any text when I run xmlindexer or rdfindexer (so that's an indication). In mln-manual.pdf, everything looks fine though but still impossible to index it.

Something else...
I don't have many strigi packages installed (like strigi-daemon) in my system but I guess I don't need them as well...
Even the package strigi-utils providing xmlindexer and rdfindexer, I had to manually install it.

Here is a list of packages and their corresponding versions in my system returned after a search for strigi.

I don't see any obvious one.

When there is output there is no obvious method but you can compare results between an indexed pdf and a not indexed a pdf and try to detect what is happening.

To complicate more this stuff indexer could be working but adding the resource to Nepomuk could fail but, at least, you can confirm that there is not a problem at indexer level.

Of course, if there is no text then indexer is failing. In my system, and with my debug level, I obtained and "Error in parsing" msg indexing your pdf.

As I explained, when I repaired the pdf indexer using pdftk there is no error parsing the file so seems like this pdf has some type of damage. As both fixed and not fixed pdfs are indexed in my system I can't confirm if a repaired pdf will be indexed in your system.

Finally about your installed versions I can't help you because I don't use Ubunto, maybe others could help you. I can only confirm you that in openSUSE 11.3 the pdf is indexed.
