[imp] VFS Sql in CVS HEAD appears broken

[rcooper at jamesconeyisland.com]

Just noticed the following problem.  Would someone care to see if they can
duplicate it?  Sending attachments over about 1mb in size with the VFS
sql driver for a mysql backend results in a truncated, zero byte file
attachment being sent to the recepient.  Using $conf['vfs']['type']='file'
works as expected.

File sizes under 1mb seem to work fine.  When this occurs there are no
error messages  or anything else to indicate there was a problem.  vfs_id
in
horde_vfs table increments, vfs_data remains either null or has an
invalid length.  Have not yet determined the exact filesize the failure
occurs.

To reproduce:

1.  Might want to truncate horde_vfs table if there are a lot of entries.

2,  Compose a mail and attach an attachment say 1.2 or 1.3 Megs or greater
in size.

2.  Click attach.

3.  run mysql client to view the vfs table contents:

	mysql -u horde -p horde
	select * from horde_vfs;

the vfs_id field increments, and all fields in table look good except for
vfs_data which is either zero, or some bogus value.  Obviously this is
when the operation was aborted or failed.

Selecting a smaller file will result in proper operation.
Not sure what to try next.  But will be glad to assist in any testing.
