Bug in ver 5.6.2.4756 -- cannot display big numbers

After update to 5.6.2.4756 the size of big files displays as a negative number.
For example, 42Gb file displays as a negative number -1,923,541,681
This was not a problem in previous versions

I cannot reproduce this problem. Local or remote side? What protocol?

OK, got it. Added to the tracker:
