[Samba] Printing is broken in rc1?

[Demchenko Yevheniy]

I have upgraded recently from alpha22 to rc1. While trying to access printer 
properties from XP, i'm getting error "Runtime Error! program: 
C:\WINDOWS\explorer.exe abnormal program termintation". Printing is not 
possible as well. This error is reproducable from any WinXP computer on 
network on any shared by samba printer. Printers are HPLJ2100, drivers are 
latest PCL6 downloaded from HP and are installed on server via Add Printer 
wizard. When i delete drivers from server and install them again, it works 
for a while until the first change in printer settings.
Any ideas? Thanks.
