largefiles, hg addremove does not want to remove ...

i tried to remove a small xml file out of the repository on windows,
and addremove does not do it. could this be a bug?

$ del conf\test.xml

$ hg st
! conf\test.xml

$ hg addremove conf\test.xml
abort: minimum size for largefiles must be specified

in the userhome mercurial.ini, and in .hg/hgrc, there is:
[largefiles]
minsize = 1

btw, hg rm removes the file without error.
