TEXTENV_INVALID in 46C dump after the apar II14126 and kernel 2341

Question

Dear all,
we got an issues after moving our prod 570 to V5R4 and applying the apar II14126 *** Last Updated 8 October 2007 *** (current) with kernel patch 2341 (current): we continuously get the dump TEXTENV_INVALID in the central instance. From my understanding now we're current with the kernel, ***, hyper, single PTFs and here's an example of the work process dev trace
A  *** ERROR => 1th error during 2th text env operation  [ablocale.c   124]
A  *** ERROR => error code       'TEXTENV_INVALID' [ablocale.c   125]
A  *** ERROR => kernel operation 'NEW MODE' [ablocale.c   126]
A  *** ERROR => platform         'OS/400A'      [ablocale.c   127]
A  *** ERROR => language         'I'          [ablocale.c   128]
A  *** ERROR => country          '   '        [ablocale.c   129]
A  *** ERROR => modifier         ''           [ablocale.c   130]
A  *** ERROR => The requeted operations wants to activate   [ablocale.c   148]
A  *** ERROR => locale 'IT_IT_ISO1'. But the operating system  [ablocale.c   150]
A  *** ERROR => rejected to do that. Please check if this   [ablocale.c   151]
A  *** ERROR => locale is installed.                        [ablocale.c   152]
A  *** ERROR => Use transaction ST22 for details.           [ablocale.c   175]
A  *** ERROR => For help look at SAP note 42781.            [ablocale.c   176]
A  *** ERROR => ---                                         [ablocale.c   177]
DLTR3PKG done multiple times, all the locales are good, we recreated them also, no luck. We NEVER experienced a similiar issue when in V5R3.
We've found a workaround by applying the following parameters in the DEFAULT profile:
abap/set_etct_env_at_new_mode = 0
install/collate/active = 0
rscp/TCP0B = TCP0C
we got rid of the dumps but is that safe ? is that ok if we run non-latin1 language, eg: cech language ? We've been reported that for the cech users the characters aren't being correctly shown.
Thank you for helping.

Dear friend,
thanks for your hints.
In the R3<SID>400 we have all the locales we need, as we used to be ! we upgraded to V5R4, no changes to the SAP instances, eg. the IT locale in R3F3C400
Opt  Object      Type      Attribute               Size  Text
     IT_IT_ISO1  *LOCALE                          12288  Created with CCSID 50
and here's the QSYSLOCALE
                               Display Library
Library  . . . . . . :   QSYSLOCALE      Number of objects  . :   4
Type . . . . . . . . :   PROD            Library ASP number . :   1
Create authority . . :   *CHANGE         Library ASP device . :   *SYSBAS
                                         Library ASP group  . :   *SYSBAS
Type options, press Enter.
  5=Display full attributes   8=Display service attributes
Opt  Object      Type      Attribute               Size  Text
     QLGMRM1     *PGM      CLP                    53248
     QLGMRM2     *PGM      CLP                    53248
     QLOCALESRC  *FILE     PF                 113676288  DATA BASE FILE FOR SY
     QLG2150     *PRDLOD                           8192
we opened a very high ticket to SAP, no proposed solution so far...
Is that possible that just an upgrade to V5R4 + apar + kernel patch is messing up all our 46C ASCII instances ?
