           Summary: email feeder creates invalid SPARQL for addresses
                    containing quoted-strings
           Product: Akonadi
           Version: unspecified
          Platform: Unlisted Binaries
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: NOR
         Component: Nepomuk Feeder Agents
        AssignedTo: tokoe at kde.org
        ReportedBy: wstephenson at kde.org
                CC: vkrause at kde.org, kdepim-bugs at kde.org


Version:           unspecified
OS:                Linux

Email addresses of the form "John Doe"@domain.org are ugly but legal.  The
extra quoting creates invalid SPARQL queries:

}' (iODBC Error: [OpenLink][Virtuoso iODBC Driver][Virtuoso Server]SQ074: Line
1: SP030: SPARQL compiler, line 1: syntax error at 'DL' before '-')"


Reproducible: Didn't try

Steps to Reproduce:
Allow folders containing mail with To: addresses of this form to be indexed.

Actual Results:  
nepomuk-email-feeder hangs and causes virtuoso, dbus and itself to uses 100%
cpu between them
