[Orgmode] C-k makes entries disappear in agenda view

[emacs-orgmode]

Hello,

As I was saying in anoter post, it looks like there's something weird
happening when using C-k in agenda view:

1. Create two new remember entries (i.e. test and test2) with the same
tag (I used @office)
2. Narrow down the agenda view to only see the @office entries.
3. Kill the last but one entry (it should be "test") : both of "test"
and "test2" disappear frow the view. Actually, "test2" is not properly
killed, but it is scary nonetheless.

It only happens with two last entries.

Is anyone able to reproduce this ?
