[ansel] Can't upload files

[Todd Aiken]

Using Ansel snapshot from last night with Horde 3.1.1, I can't upload any 
of my images to galleries that I create.  I keep getting the error message:

There was a problem saving the image: unable to create VFS directory.

VFS is setup in Horde to use the filesystem at /tmp, and I can see that it 
is working as there are other files there from other applications (eg: 
scheduler).

Tried configuring VFS in Horde setup to use my local MySQL database, but I 
get the same error message.

Any ideas?
