[Nepomuk] nepomukserver error output in KDE 4.8

[S Page]

Updating to  Kubuntu 12.04 Alpha 2 fixed several Nepomuk errors
(yay!), but running  `nepomukserver --nofork` , I still see lots of
errors fly by.  (BTW, it would be great if the debugging guide in
http://kdeatopensuse.wordpress.com/2011/11/09/debugging-nepomukvirtuosos-cpu-usage/
was in a wiki page on techbase).

Here are some I noticed.

1. something about not handling a slant property.

2.I get lots of "Unknown protocol '' encountered in 'John Doe
<jdoe at example.com>'." errors indexing old imap e-mail folders:

[/usr/bin/nepomukservicestub] "/usr/bin/nepomukservicestub(3058)"
Soprano: "Invalid argument (1)": "Unknown protocol '' encountered in
'John Doe <jdoe at example.com>'."
[/usr/bin/nepomukservicestub] nepomukindexer(3366)/nepomuk (strigi
service) Nepomuk::StrigiIndexWriter::finishAnalysis: "Unknown protocol
'' encountered in 'John Doe <jdoe at example.com>'."

If I run nepomukindexer by hand on this message
blahblah/mail.imapmbox/CachedMessages/2060 , I can reproduce the
second message.

3. Some errors indexing .flac file:
[/usr/bin/nepomukservicestub] "/usr/bin/nepomukservicestub(3058)"
Soprano: "Invalid argument (1)": "Failed to convert '-1.17 dB' to
literal of type 'http://www.w3.org/2001/XMLSchema#float'


4. A few of these, I assume from pictures

[/usr/bin/nepomukservicestub] "/usr/bin/nepomukservicestub(3058)"
Soprano: "Invalid argument (1)":

6.Errors indexing a Trac roadmap exported as iCalendar, e.g.

Hmmm.
