Dear Yves-Alexis,

sorry for the late reply.

I still experience this. Sometimes more, sometimes less. I even was able
to reproduce this on a different system. Most developers do not seem to
use Evolution and prefer mutt or Icedove. So I claim, that is the reason
that this is not noticed this much. Non-developer users just start
Evolution from the icon and do not know how to report bugs.

Actually only if you are lucky. It seems auto-saving only happens after
x minutes and if you type fast or copy something in that interval and
delete the source before the x minutes are over the data is lost.

As written above. I now found two (over four years old) systems that
show this behavior. Do you have a lot of IMAP and POP3 accounts?

Here some more information.

1. The crash never happens when being offline. Therefore I start
Evolution using `evolution --offline`.

2. The crash happens more often, when trying to compose a message (Ctrl
+ r or Ctrl + n) when just going online and a lot of messages (from
lists) are downloaded.

I am pretty sure there is a memory leak somewhere, as I get segmentation
faults and bus errors. Unfortunately Valgrind seems to have a bug, where
it does not find installed debugging symbols [1]. So this does not get
me further.

Here is an excerpt from `/var/log/kern.log`.

Due to the Valgrind bug [1] I am currently stuck with debugging this. So
any help is appreciated.

Thanks,

Paul
