No Samuli,
There is no dump in ST22. As I mentioned earlier, it works in IE8, so I can't imagine why there should be a dump in ST22.
I checked the Product Availability Matrix in service maketplace and here's what I found:
This tells me that Google Chrome is compatible with ABAP Technology for ERP EhP6.
And just to clarify, the 4.7 Version still exists and Chrome works well in there.
Regards,
