[PD] Tcl/Tk error in slop~ helpfile

hi,

i'm getting a TCL/TK error in the PD console window when i click on the "open HTML documentation in help browser" button in the helpfile for the new [slop~] object:

(Tcl) UNHANDLED ERROR: wrong # args: should be "::pd_menucommands::menu_openfile filename" while executing "::pd_menucommands::menu_openfile C:/Program Files/Pd/doc/5.reference/../8.topics/slop-tilde.htm" ("uplevel" body line 2) invoked from within "uplevel #0 $docmds"

this is with a freshly installed PD 0.50 in windows (installer version) and i'm pressty sure it's because of the space in the path. because when i do the same with the standalone (.zip) version, where i don't have paths with spaces in it, the error doesn't occur.

best
