[imp] VFS problem

[Mannel Chan]

Hi all, 

Can anyone answer my question?? I would like to know if anyone here has tried 
the VFS function in Horde and IMP!? After enable it in IMP, I can't attach any 
file to the mail. But it works fine if I turn it off. I've tried both 
the 'file' and 'sql' drivers for the VFS, the results are the same. And there's 
no error log. Instead, I got a warning message in the php error.log when I use 
the 'file' driver. Here's the message: 

PHP Warning:  Object to string conversion 
in /var/www/html/mail/horde/imp/compose.php on line 356 

For the 'sql' driver, I did create the horde_vfs table using the script 
provided in Horde. Anyone can help? Btw, is there any performance advantage for 
VFS over non-VFS?

And here're my configurations: 

Horde: 2.2.3 
IMP: 3.2.1 
Turba: 1.2 
Passwd: 2.2 
Kronolith: 1.1 
Mnemo: 1.1 
Nag: 1.1 
Accounts: 2.1 
Forwards: 2.2 
Vacation: 2.2 

OS: Redhat 7.3 
Apache: 1.3.27 
PHP Version: 4.1.2 
Latest PEAR from the Horde website
