Possible bug with removing files?

[Andrew King]

Hi,

Someone complained that a file is missing from our repository. I am
not sure if I have found a bug or not ...

(aside ... is it desired behaviour that doing bzr log "myRemovedFile"
gives no information? It is very very difficult to find out which
revision caused a missing file).

Eventually, after doing bzr diff down numerous revisions, I found a
place where the file got removed ...

bzr diff -r886.1.62..862.1.114.1.74.1.38.1.9 | grep myFileName

shows file missing

=== removed file 'myFileName'
--- myFileName  2007-08-28 03:59:02 +0000
+++ myFileName  1970-01-01 00:00:00 +0000
@@ -1,51 +0,0 @@

However,

bzr log -v -r886.1.62..862.1.114.1.74.1.38.1.9 | grep myFileName

does not return anything! In other words, diff shows the file being
removed without any commit in that area removing the file?!

Can anyone explain this please, or help me fix it?

Regards,
Andrew.
