[imp] VFS problem

[=?big5?b?sWmofaTl?=]

Hi there:
I have a VFS (MYSQL backend) problem in IMP 4.0 CVS.
Maybe someone can help to fix it or give me a hit where to start hack it.

Situation is :
I use VFS as attachments store backend in IMP compose,everytime i try to attach
*BINARY* file then got this error message,
DB Error: syntax error

Only BINARY file cause this problem,text file is ok,In /tmp/horde.log i saw
"INSERT INTO horde_vfs ........" so i thnk during binary file encode IMP made
some single quote(or double quote) in the INSERT statement and cause error.

Other information/Configuration could be found here:

Thanks you .
