Error in DDL upgrade

[Thunderstick]

Hello,

everytime i run the update script there is the following error at the end:

Code: [Select]

Running update script at target...
Executing database schema update.
ERROR: Error in DDL upgrade 2013052500: [1050] Table 'cache_shared' already existsUpdating database schema (2013052500          )... [FAILED]
All done.

It seems the update finished successful, but i get this error on every upgrade. Now upgrading to 1.0.5, before 1.0.4, ...
Why appears this error every time?
