[Wine] not enough disk space

[tolosthemagician at gmail.com]

ok, this is a problem I've been having reguardless of what program I
try and install -- running programs works fine, but not installing
them.

The problem is when I try and install a program using wine, it says
that there is not enough disk space.  This doesn't really make sense as
I've got loads of disk space all over the place:

/ -> 45gb free
/mnt/max40 -> 5gb free

wine's windows drive is locate on / at /home/tolos/.wine/drive_c/

but... there's more!

not only does a wine trying-to-install app fail to find my free space,
but it reports it wrong:

/ is reported as having ~680mb free
/mnt/max40 is reported as having ~2.7gb free

normally I would include any error messages, except, there are none.
The program will run fine, then complain about not having free space,
then exit.

wine version 0.9.19 with
http://www.thehandofagony.com/alex/wine/patches/wow-patch-0.9.18.diff
patch to play world of warcraft. (yes the patch file name
'wow-patch-0.9.18.diff' is correct)

kernel version 2.6.17.11 on debian testing

any help would be appreciated.
