[TYPO3-install] Upgrade 4.3->4.5 renders backend inaccessible

[Patrick Hunziker]

Hi all
thanks, Ki Hyoun, for the advice - is this a general advice or a 
specific problem with 2-level upgrades ? As I have only slow FTP to the 
hosted server, each version upload costs me several hours, and I have 
already invested many hours so I would like to understand first a little 
better where the problem is. Therefore, I have now tracked the exception 
source using debug output:
does this help in understanding to others - I am a little lost.
Thanks
Patrick
