[Samba] Printer driver upload from WindowsXP is broken since 3.0alpha22

[Demchenko Yevheniy]

Recently i've moved to samba 3.0 beta1 and noticed, that drivers for shared 
printers couldn't be uploaded from WindowsXP GUI any more. After copying 
files to \\smbserver\print$\W32X86 folders it says something like "Unable to 
install HP LaserJet 2100 PCL6, Windows2000 or XP, Intel driver. Operation 
could not be completed".
It works OK on samba3.0alpha20, but doesn't work on samba3.0alpha22-24.
Uploading from Windows2000 is OK.
Is it Samba bug or i'm missing something?
Thanks.
