 I saw this bug report to pyfilesystem:

 {{{
 tahoe-lafs 1.9.0 + pyfilesystem 0.4 (and svn r723) + dokan 0.6.0

 As far as I know, pyfilesystem doesn't have a strong test suite, so it
 will require more effort from someone to figure out where exactly the
 problem lies in pyfilesystem, Tahoe-LAFS, dokan, or the interfaces between
 them...
