Description Simon Solinas 2013-09-17 16:33:26 UTC

if I look at the title of a pdf file into the information panel, this consists by the real title followed by a series of strange characters ( perhaps Chinese, Japanese, Korean or unknown)

Reproducible: Sometimes

Steps to Reproduce:
1. open or create a simple pdf file with Calligra Word or LibreOffice Write.
2. select the pdf file 
3. look at the information panel

Thanks for the bug report. Please always include a screenshot when you see something strange in the application. I'm not quite sure if you refer to the preview image (in that case, it would be a problem with the thumbnailer) or to the title of the PDF file (in which case it might be a Nepomuk problem).

It would also be good if you could attach a problematic file, because I could not reproduce any problems with a few test files yet. Thanks for your help!

Screenshot is present in the URL section  above. Nepomuk is disabled. I don't know how I could create a problematic file in this case.

Thanks for the quick reply.

Oops, sorry, I must have missed that! Sorry about that.

If I'm not mistaken, this information inside the Information Panel is provided by Nepomuk even if the indexer is disabled, so I'll reassign.

> I don't know how I could create a problematic file in this case.

Well, if "thisisatest.pdf" does not contain anything private, you could attach it here.

Comment 6 Christoph Feck 2013-09-17 23:02:26 UTC

Another test file can be fetched from http://www.mabb.de/files/content/document/Foerderung/mabb_Broschuere_OER_in_der_Praxis.pdf

It displays "Title: Offene " followed by many garbage characters (looks like binary), actual title should be "Offene Bildungsresourcen (OER) in der Praxis".

Comment 7 Christoph Feck 2013-09-18 01:21:48 UTC

Interesting detail: If I hover over the PDF from comment #6 forth and back multiple times, the "Title: Offene" is constant, while the garbage that follows it changes randomly, so it looks like the parser references random pointers.
