      Type:  defect         |       Status:  new    
  Priority:  normal         |    Milestone:         
 Component:  Cabal library  |      Version:  1.8.0.2
  Severity:  normal         |     Keywords:         
Difficulty:  unknown        |   Ghcversion:  6.12.1 
  Platform:  Windows        |  
----------------------------+-----------------------------------------------
 Distribution.Simple.InstallDirs.defaultInstallDirs fails if
 getAppUserDataDirectory fails, and it does so with a very uninformative
 error:
 {{{ # On Cabal 1.8.0.2:
 cabal.exe: illegal operation
 }}}

 This is a slight regression from the HP 2009 version:

 {{{ # On Cabal 1.6.0.3:
 cabal.exe: System.Directory.getAppUserDataDirectory: unsupported operation
 (unsupported operation)
 }}}

 This happens on Windows Vista, in cygwin, when the user doesn't have a
 windows user directory (eg: c:\users\username ).
