Hmm... okay. Thats a good point of view.

I was constantly editing my contacts the last 2 weeks, because the N900
Contacts Application is not as flexible as the one known from Symbian Devices.
So I'm still comparing and fixing contacts when I had time. Many informations
are still only on my old Nokia N95 stored. 

I had a reboot of the device the day before using the Media Player. I tested a
Video with a very high bit rate. Hm, to high I guess. 
But this is not the topic of this Bug report. It could be possible that the
contacts application and some communicatins were still running when the reboot
appears. :-/

Could a not stored cache of the Contact Database caused such a bug?

When I take a look into the Backup Files. It seems that the Contacts are stored
in: 
"Root\home\user\.osso-abook\db\backup.vcf"
and the SMS Messages in:
"Root\home\user\.rtcom-eventlogger\backup.db"

I guess the backup.db is a direct copy of the internal database. 
Is the backup.vcf a direct copy of the internal stored File or is this a export
and during restoring the Contacts are parsed in some way?

I had only the Backup of the Conversations and Contacts. The bug is gone. :-(

I tryed to check the Database file of the backup, but I can only look with a
hex editor at the SQLite Database.
I can find the String "ring/tel/ringT-Mobile" and even on some places
"ring/tel/ring2000". But nowhere a number or a part of one from "Alexander K.".
I had no contact to this person for more than a year. So no SMS send or
received from this guy on this device. It seems there is nothing stored in the
backup.db file that points to the Contact "Alexander K.".

I checked the part of "Alexander K." in the vcf file line for line. Even the
rest of the file seems okay. The File is with 43686 Bytes large but okay. I
collected 255 Contacts the last 10 Jears. But I read from users with more than
800 contacts. So this shouldn't be a problem.

After restoring the backup once everyting is still fine. :-/
But I restored a Backup taken AFTER the Bug appears. I can't understand.

I'm sorry to waste your time! :-(
