[TYPO3-dev] Error migrate image during upgrade TYPO3 from 4.5 to 6.2

[Web Essentials - Support (Phallin Hor)]

Dear list,

I got problem during upgrade from TYPO3 4.5.34 to TYPO3 6.2.4. I follow 
the steps here 
http://docs.typo3.org/typo3cms/InstallationGuide/UpgradeLTS/Index.html. 
I did not use DAM extension.

Everything works fine except "Migrate all RTE magic images from 
uploads/RTEmagicC_* to fileadmin/_migrated/RTE/" in upgrade wizard. I 
got warning and error below:
- Warning before execute migration: "Updating the reference index
This script bases itself on the references contained in the general 
reference index (sys_refindex). It is strongly advised to update it 
before running this wizard." There are currently 34 magic images in the 
old directory.

- After I run execute I got

Detected Fatal Error

on line 1082

I also got the same error when access filelist in backend.

I update the reference index again and also follow the step here 
https://forge.typo3.org/issues/61154. I have changed permission for both 
typo3 source and  rood directory to 775. The patch here 
https://forge.typo3.org/issues/53802 is also applied already for 6.2.4 
but the image migration still not success.

Thank you in advance for your help.

Cheer,
Phallin
