WindowMaker-0.61.1 errors on current

Hi all.
After updating system to current and recompiling ports tree
about 3 weeks ago, WindowMaker not works properly.
After xsession startup I have the following info in ~/.xsession-errors:
-- begin cut
/home/users/pvk/GNUstep/Defaults/WMGLOBAL:line 2: syntax error
/home/users/pvk/GNUstep/Defaults/WindowMaker:line 2: syntax error
wmsetbg warning: could not open domain file /home/users/pvk/GNUstep/Defaults/Win
dowMaker
/usr/local/share/WindowMaker/Defaults/WindowMaker/WindowMaker:line 2: syntax err
or
/home/users/pvk/GNUstep/Defaults/WindowMaker:line 2: syntax error
wmsetbg warning: could not open domain file /home/users/pvk/GNUstep/Defaults/Win
dowMaker
/usr/local/share/WindowMaker/Defaults/WindowMaker/WindowMaker:line 2: syntax err
or
/home/users/pvk/GNUstep/Defaults/WMState:line 2: syntax error
-- end cut

WindowMaker compiles cleanely, i think the problem is in libproplist,
but due to my poor programming skills, I can't catch, where error exists.
May be anybody solve this problem?
Thanks in advance.
