Mutt status lines under GNU/screen

[Chris Jones]

The mutt mailer displays by default two one cell-high bands at the top
and bottom of the screen, something that looks a bit likes so:

│ ▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄▄

I have an ongoing problem where the rightmost part of the top and bottom
bands are truncated to a variable percentage of their lengths, like so:

│ ¹ truncation 

This only concerns the top and bottom status bars, never the one in the
middle, it can be reset via Ctrl-L, and though I have not been able to
find a pattern, it only appears when switching to another X virtual
desktop - wmaker workspaces, in my case - or when switching back and
forth between GNU/screen "windows", via e.g. Ctrl-G n / Ctrl-G p.

I have failed to reproduce under an xterm without screen, and so I
assume that the issue is related to GNU/screen.

Since it does not happen with comparable programs such as slrn, or Vim,
I should probably take this to the mutt list, but thought maybe someone
here may have found an explanation for this.

I should add that I use the vanilla screen-256color-bce entry that ships
with debian lenny:

│ $ dpkg -l ncurses-base
│ ii  ncurses-base   5.7+20081213-1    basic terminal type definitions

Thank you for your comments,
