Summary: jet40 installer complains not enough disk space
           Product: Wine
           Version: 1.1.9
          Platform: Other
        OS/Version: other
            Status: NEW
          Keywords: download, Installer, regression
          Severity: normal
          Priority: P2

'winetricks jet40' ought to install jet, but now jet puts up an
error dialog, saying "setup could not find a drive with 23829 KB
free disk space to install the program".
This is on a system with quite a bit of free space:

$ df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/sda1             10325748   3471724   6329504  36% /
/dev/sda5             62459296   8938064  50348400  16% /home

so something is amiss.  I've never seen it before, so tagging with 
'regression'.
