That seems to agree with my observations.  This morning, I even saw it using 
78% CPU, while the popup said that it was waiting for 'something' to happen.  
I didn't see any indication what that 'something' might be.

I tried the command recommended by techbase (with kontact closed, of course).

qdbus org.kde.NepomukServer /nepomukserver     org.kde.NepomukServer.quit

After which I saw several instances of:

Nepomuk Indexing Agents Have Been Disabled
The Nepomuk service is not available or fully operational and attempts to 
rectify this have failed.  Therefore indexing of all data stored in the 
Akonadi PIM service has been disabled, which will severely limit the 
capabilities of any application using this data.

The following problems were detected:
  * Nepomuk is not running.

Additional help can be found here:  userbase.kde.org/Akonadi

So then, to restart it:

nepomukserver
Nepomuk server already running.

All of which is confusing, to say the least.  By now, though, I'm totally 
convinced that this is where the problem lies.  Ksysguard shows Nepomuk CPU 
usage shooting up every time I have a KMail freeze.
