OCI_INVALID_HANDLE updating BLOB in Typo3/PHP

Question

Hi all,
We're busy with implementing Typo3 (OpenSource CMS in PhP) on Oracle (XE universal).
We're running in a OCI_INVALID_HANDLE problem during page refreshes (CTRL-Refresh).
The actual error is:
Warning: OCI-Lob::save() [oci-lob.save]: OCI_INVALID_HANDLE in /var/www/sources/typo3_src-4.2.10/typo3/sysext/adodb/adodb/drivers/adodb-oci8.inc.php on line 696
The piece of code where it refers to is:
     function UpdateBlob($table,$column,$val,$where,$blobtype='BLOB')
          //if (strlen($val) < 4000) return $this->Execute("UPDATE $table SET $column=:blob WHERE $where",array('blob'=>$val)) != false;
          switch(strtoupper($blobtype)) {
          default: ADOConnection::outp("<b>UpdateBlob</b>: Unknown blobtype=$blobtype"); return false;
          case 'BLOB': $type = OCI_B_BLOB; break;
          case 'CLOB': $type = OCI_B_CLOB; break;
          if ($this->databaseType == 'oci8po')
               $sql = "UPDATE $table set $column=EMPTY_{$blobtype}() WHERE $where RETURNING $column INTO ?";
          else
               $sql = "UPDATE $table set $column=EMPTY_{$blobtype}() WHERE $where RETURNING $column INTO :blob";
          $desc = OCINewDescriptor($this->connectionID, OCID_LOB);
          $arr['blob'] = array($desc,-1,$type);
          if ($this->session_sharing_force_blob) $this->Execute('ALTER SESSION SET CURSOR_SHARING=EXACT');
          $commit = $this->autoCommit;
          if ($commit) $this->BeginTrans();
          $rs = $this->_Execute($sql,$arr);
          if ($rez = !empty($rs)) $desc->save($val); ##################### this is line 696
          $desc->free();
          if ($commit) $this->CommitTrans();
          if ($this->session_sharing_force_blob) $this->Execute('ALTER SESSION SET CURSOR_SHARING=FORCE');
          if ($rez) $rs->Close();
          return $rez;
I've googled around for some time and also queried this forum, but could not find any suggestions. To me it seems quite ok what is done here. And it is some standard Typo3 code.
Could you please shine your light upon it and maybe give me some ideas to solve this?
Thank you very much.

Martien
