Mdworker deny file-read-data, what does it really mean?

Question

I get numerous log posts like this:
3/17/14 7:22:57.561 AM sandboxd[5688]: ([4412]) mdworker(4412) deny file-read-data /Volumes/Time Machine Backups/Backups.backupdb/Jack Shelton’s iMac/2014-03-17-042247/JackHD/System/Library/Fonts/TimesLTMM (import fstype:hfs fsflag:4809018 flags:48200000056 diag:0 uti:com.apple.font-suitcase plugin:/Library/Spotlight/Font.mdimporter - find suspect file using: sudo mdutil -t 235288)
My questiions are:
What is being sandboxed, the mdworker or the file Times LTMM or the mdimporter?
Which one has the sudo command in it?
What does the -t flag/option mean?  Looking it up via man mdutil in the terminal, it does't exist.
I saw this type of post quite frequently in Mavericks so much so that I decided to start over from scratch.  I wiped the HD including the HD Recovery partition and installed OS X 10.6.8.  I am now in Mountain Lion and have reinstalled MS Office 2011 and loaded the main identity data from my recovered files.  I did not see any adverse log posts until I ran the first time machine backup.
I hope someone can clear the air for me with perhaps a way to fix it.

Thank you Baltwo.  It's a major relief to know that the sudo command is being used by an Apple app/process and not by a file that's not supposed to have it..  However a few more questions if you don't mind.
Is the font file the suspect file or is it this particular mdworker?
If the font file is the suspect file will a process or app that calls for it be allowed to use it?
Which process/app/file invoked the sandbox and deny file-read-data?
What is the role of the mdimporter?
These questions are part of my attempt to understand how a large part of the files on my computer and Time Machine become corrupted when I first installed Mavericks.  Mainly .plist (and other plain text files), .png, jpeg (and other picture types) and pkg info bundles would have thier icons and file Kind changed to Unix Executable files, spreadssheets and doc/docx would become genrandom (or something similar).  I became aware of this when my machine began freezing up.  I made several clean reinstalls and the problems would reoccur on plugging in the Time Machine.  I eventually recovered the files I wanted from the Time Machine but I had to use another iMac with an older OS X.  I repartitioned my machine and rebuilt it to Mountain Lion and i'm in the process of reloading with what I hope are non corrupted files. Although I still see log posts like "Locum[6230]: Connection with distnoted server was invalidated" every time I paste a folder or file.  I don't know what that means but it doesn't seem to cause any further reaction or posts.
My apologizes for bothering you with alll this and thanks for your insight.
