Bug in setup 2.510.1.2

[André Bleau]

Sorry to rain on the parade, but the new version of setup has a serious bug; 
it crashes when checking the integrity of .bz2 files.

Steps to reproduce:

Launch setup from explorer.
Press Next >
Select "Download Without Installing"
Press Next >
Select E:\CygwinDownload as Local Package Directory
Press Next >
Select Use IE5 Settings
Press Next >
Select http://mirrors.rcn.net as the download site
Press Next >

I get to a page displaying:

Parsing ini file
setup.bz2
0 0.0 kb/s

Then an error dialog pops-up:

---------------------------
Cygwin Setup

Fatal Error: Uncaught Exception
Thread: DialogProc
Type: 9Exception
Message: Package validation failure for
