Could not run Sparql query: 1.182: syntax error, unexpected character

[Mike Mol]

I'm unable to select various documents. For example, I have the Debian Administrator's Handbook in my library. If I use tracker-needle to search for "samba", this shows up in the result set. *However*, if I click on this result, a message box appears:

  Could not retrieve tags for the current selection:
  1.182: syntax error, unexpected character

And the following is emitted to the console:

(tracker-needle:8238): Tracker-WARNING **: tracker-tags-view.vala:700: Could not run Sparql query: 1.182: syntax error, unexpected character

Similar errors occur with other documents. For example, the EPUB form of "Windows Server 2008: The Definitive Guide" results in "(tracker-needle:8238): Tracker-WARNING **: tracker-tags-view.vala:700: Could not run Sparql query: 1.137: syntax error, unexpected character)

Actually, a *lot* of the documents give the 1.137 variant on the error, including the PDF version, "Windows Server 2008_ The Definitive Guide.pdf", "Backup & Recovery.pdf", "Backup _ Recovery.PDF", the EPUB "Using Samba, 3rd Edition", "Using Samba, 3rd Edition.PDF", "Linux Networking Cookbook", "LINUX Networking Cookbook", "LDAP System Administration", "Managing NFS and NIS, 2nd Edition", "Managing NFS and NIS, 2nd Edition.PDF", "Red Hat Enterprise Linux 6 Administration" (and a listing document listed with the same title) and "Essential System Administration, 3rd Edition"

Hi there Mike, I am the upstream maintainer. Are you able to find out what SPARQL query is being used here? If you need help with how to do that, let me know what process you're using and I can assist! :)

Thanks for reporting the bug!

This was while using libtracker on Ubuntu 13.10, IIRC. I don't
remember the search tool; something very simple and basic, as I don't
typically use desktop environments. I don't remember much more, but
when I dug into it I remember getting the impression it was likely
because of the API's lack of query parameter binding. I don't remember
much more, sorry; it was six months ago.
