autodetection of project under subversion control failing?

hi,
 
 with build 0.9.34 I'm seeing the error message attached. The scenario
is
 
    1) have a project which already has .svn directories
    2) create an eclipse project pointing to that location
    3) do a Team -> Share action
    4) subclipse correctly says "this project already has .svn
directories, would you like to connect to it?"
    5) click yes, and get the error message
 
this only happens for two particular projects i have, but i'm not sure
what distinguishes them, so i'm only really asking if anyone else has
seen this or if there is a workaround?
 
thanks,
Andrew
