Weird file size after installing 3.0.10

[Zoë]

Thanks for the bug report. The issue will occur for files larger than 2GB that have a '0' in the hundred millions position. We'll have it fixed in the next release.

For one of the files, BC 3.0.10 shows file size as (386,925,824 bytes) instead of (3,086,925,824 bytes). Reinstalled previous version (3.0.9) - the problem disappeared. Can you please check what could cause this. Thanks!
