Deregistering a font with NSIS - nsis

Question

When I try to uninstall a font like that...
Section "un.Uninstall"
StrCpy $FONT_DIR $FONTS
!insertmacro RemoveTTFFont "$FONTS\Vani.ttf"
!insertmacro RemoveTTFFont "$FONTS\Vanib.ttf"
SendMessage ${HWND_BROADCAST} ${WM_FONTCHANGE} 0 0 /TIMEOUT=5000
SectionEnd
I get the following error message:
Error in macro GetFileNameCall on macroline 2
Error in macro RemoveTTFFont on macroline 9
(...) aborting process
In other words, there's something wrong with the following section in the FontReg.nsh file:
!ifmacrondef GetFileNameCall
!macro GetFileNameCall _PATHSTRING _RESULT
Push `${_PATHSTRING}`
Call GetFileName
Pop ${_RESULT}
!macroend
!endif
!ifndef GetFileName
!define GetFileName `!insertmacro GetFileNameCall`
Function GetFileName
Exch $0
Push $1
Push $2
StrCpy $2 $0 1 -1
StrCmp $2 '\' 0 +3
StrCpy $0 $0 -1
goto -3
StrCpy $1 0
IntOp $1 $1 - 1
StrCpy $2 $0 1 $1
StrCmp $2 '' end
StrCmp $2 '\' 0 -3
IntOp $1 $1 + 1
StrCpy $0 $0 '' $1
end:
Pop $2
Pop $1
Exch $0
FunctionEnd
!endif
Can someone, if not tell me how to fix the bug, at least point me in the right direction?
It would be useful for the community as many have had this problem but no one has solved it yet, like here - http://forums.winamp.com/showthread.php?t=245701

I haven't received any answers unfortunately, but I must share the solution I came up with, since I saw that lots of people have had the same problem.
There is a bug in macros to remove fonts, namely "RemoveTTF", "RemoveTTFFont" and similiar sounding ones in the following files : FontReg.nsh, FontRegAdv.nsh. All of them use the same function called "GetFileNameCall" which causes the error. The problem with this function is that it sees "FontName" and "FontFileName" as the same item! As a matter of fact, font file name differs from font name. I solved the problem by copying the needed code from FontRegAdv.nsh and replacing FontFileName and FontName variables with the actual font file names and font names.
