Not much, other than I notice that the manner in which hg data is stored 
makes special treatment of capital letters, i.e., a capital letter is 
represented as _o instead of O.  So, in this case:

[sebal .hg]$ ls store/data/build-aux/*ava*
store/data/build-aux/_oct_java_qry.class.i
store/data/build-aux/_oct_java_qry.java.i

With that in mind, I wonder if there is an "OctJavaQry.class" in the 
database somewhere...and there might be:

address@hidden .hg]$ grep Java */*
store/fncache:data/build-aux/OctJavaQry.java.i
store/fncache:data/build-aux/OctJavaQry.class.i

Perhaps Mercurial believes

   store/fncache:data/build-aux/OctJavaQry.java.i

is illegal because it should be

   store/fncache:data/build-aux/_oct_java_qry.java.i

inside of "store/fncache".

If this is the case, how this came about, I can only guess.  Perhaps 
this is a Windows/others issue because of DOS ignoring case or 
something?  Maybe the Mercurial settings on Rik's machine are different 
than yours?  (guessing!)  Might there be a command line switch 
controlling how upper case letters are treated in the database?
