* weird emacs bugs causing data lossage
<2011-04-10 Sun>
the journal.organisation file gets cropped to only these two
characters; **

it happens when I do an org capture and org narrows the
buffer. the croping happens on disk for some reason which emacs
detects. Maybe autosave didnt understand the buffer narrowing.

Emacs ask if I really want to edit the buffer and I say
no. Then Emacs redisplay seems to hang.

This happened several times. Most times I had to kill emacs and loose
my work. This time I tried more debugging. Lately I run Emacs in a
debugger. Weirdly gdb refused to break itho a prompt. ctrl z and fg
woke up gdb. Then I tried strace and noticed emacs was polling a
select repetadly which is maybe normal. The broken emacs was still
stuck at the minibuffer prompt. 

it occured to me that maybe Emacs wasnt totaly hung maybe just
redisplay. So I tested emacs client and I could recover data like
this:

 emacsclient -e "(let ((b (set-buffer \"journal.org\")) (text  (buffer-string))) (set-text-properties 0 (length text) nil text)text)"

There are two weird things here:
- the file was truncated. Maybe this is due to a combination of
  narrowing and automatic save.
- redisplay hangs in minibuffer input. I have no idea about why this
  happens.

So. Probably several strange bugs conspiring together.
