Mutt stops showing mail contents

[Josef Wolf]

Here I am again.

I got the problem again. More information below. First answers to questions:

This shows the whole message, includug body.

No. Body is still not shown.

No leaked file descriptors there.

Yes, attribution header is there. But no quoted content.

Yes.

With attachments, I have screwed a little bit up:

- when a message is shown (before pressing 'v'), the red markers like
  "[-- Attachment #1 --]" are also missing.

- when pressing 'v', the attachments are shown and can even be saved.

Sorry for the confusion!

More info:

Last time, as mutt was working, memory looked like this:

  raven:/ # ps axl|grep -v grep |egrep  ' (mutt|COMMAND)'
  F   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND
  0  1000  1135 19716  20   0  97188 21104 SyS_po S+   pts/3      0:00 mutt
  0  1000 15559  6391  20   0  97260 21124 -      S    pts/2      0:00 mutt


  raven:/ # ps axl|grep -v grep |egrep  ' (mutt|COMMAND)'
  F   UID   PID  PPID PRI  NI    VSZ   RSS WCHAN  STAT TTY        TIME COMMAND
  0  1000  1135 19716  20   0  97488 21388 SyS_po S+   pts/3      0:00 mutt
  0  1000 15559  6391  20   0  97352 21232 SyS_po S+   pts/2      0:01 mutt

So size has increased a little bit, but not very much

Here are the open descriptors. The deleted file is the one which is currently
shown in mutt:
  
  raven:/ # ls -l /proc/15559/fd
  total 0
  lrwx------ 1 jw jw 64 Dec 20 19:50 0 -> /dev/pts/2
  lrwx------ 1 jw jw 64 Dec 20 19:50 1 -> /dev/pts/2
  lrwx------ 1 jw jw 64 Dec 20 19:50 2 -> /dev/pts/2
  lr-x------ 1 jw jw 64 Dec 20 19:50 3 -> /tmp/mutt-raven-1000-15559-7436415611661510353 (deleted)


This deleted file is also missing the mail body:


  raven:/ # cat /proc/15559/fd/3
