[Samba] filenames with ":"

[joe piscitella]

I have been reading everything I can to figure out how to get SAMBA to accept a filename with a ":" in the name.
I am running Gallery on my FREEBSD mahine that using SAMBA to connect to the windows machine.  Gallery generates 
filenames with a : in the name

Example : 1023493:239434.0.  When you try to create a file with a : you get the following error:

$ touch 1:2
touch: 1:2: No such file or directory

I am currently running Samba 2.2.8.

I have tried both valid_chars and client_code_page in smb.conf and still no luck.
