[horde] Bug in Horde 4.0 RC and IMP 5.0 RC2

[Juan C. Blanco]

Hello I've added INGO 2.0.0RC2 to my tests of new version of HORDE, 
testing the creation a new rule I have two different problems:

First there is two log error messages

Apr  3 18:33:05 xweb HORDE: HORDE [ingo] PHP ERROR: Undefined index: a 
[pid 24593 on line 105 of "/srv/www/htdocs/horde/ingo/lib/Storage/Sql.php"]
Apr  3 18:22:33 xweb HORDE: 1. Ingo::updateScript() 
/srv/www/htdocs/horde/ingo/rule.php:139 2. Ingo_Script_Sieve->generate() 
/srv/www/htdocs/horde/ingo/lib/Ingo.php:259 3. 
Ingo_Script_Sieve->_addForwardBlocks() 
/srv/www/htdocs/horde/ingo/lib/Script/Sieve.php:581 4.

/srv/www/htdocs/horde/ingo/lib/Script/Sieve.php:218 5. 
Ingo_Storage_Sql->_retrieve() 
/srv/www/htdocs/horde/ingo/lib/Storage.php:138 6. Horde::errorHandler() 
/srv/www/htdocs/horde/ingo/lib/Storage/Sql.php:105

[pid 24468 on line 106 of "/srv/www/htdocs/horde/ingo/lib/Storage/Sql.php"]
Apr  3 18:22:33 xweb HORDE: 1. Ingo::updateScript() 
/srv/www/htdocs/horde/ingo/rule.php:139 2. Ingo_Script_Sieve->generate() 
/srv/www/htdocs/horde/ingo/lib/Ingo.php:259 3. 
Ingo_Script_Sieve->_addForwardBlocks() 
/srv/www/htdocs/horde/ingo/lib/Script/Sieve.php:581 4. 
Ingo_Storage->retrieve() 
/srv/www/htdocs/horde/ingo/lib/Script/Sieve.php:218 5. 
Ingo_Storage_Sql->_retrieve() 
/srv/www/htdocs/horde/ingo/lib/Storage.php:138 6. Horde::errorHandler() 
/srv/www/htdocs/horde/ingo/lib/Storage/Sql.php:106

Second, I receive a Fatal Error excepcion message

Fatal error: Class 'Ingo_Script_Sieve_Action_RemoveFlag' not found in 
/srv/www/htdocs/horde/ingo/lib/Script/Sieve.php on line 501

In this case I supose that in this line the name of the class must be
'Ingo_Script_Sieve_Action_Removeflag' that is how is declared in 
ingo/lib/Script/Sieve/Action/Removeflag.php
