Somebody speaking Log-Chinese?

[Stefan Daehler]

For the last ten or so days I constantly have an ErrorLog.txt on my 
system-disk, complaining about as follows:

"Fri May 28 07:22:22 CEST 2004 PersistenceItem:SaveObject:Filestream: 
java.io.StreamCorruptedException: Caught EOFException while reading the 
stream header
Fri May 28 07:22:22 CEST 2004 PersistenceItem:SaveObject: 
java.lang.NullPointerException"

Can somebody tell me what this means in common language? The log can be 
trashed (with administrator-password) but after the next reboot it's 
again there.

(Yikes!, G4/600, 512 MB RAM, Mac OS X 10.3.4)

Thanks for caring!     Steff
