I'm getting relatively frequent (a few a day) core dumps from evo-
exchange backend. Here's a sample:

Looking at the source code it appears to be dying here:
} else {
SoupBuffer *response;
status = e2k_context_get (mse->ctx, NULL, mmsg->href,
&content_type, &response);
==> len = response->length;
body = g_strndup (response->data, response->length);
soup_buffer_free (response);
}
Apparently e2k_context_get() failed which means response was not set,
but this is not checked for by the code:
(gdb) thr 2

in mail-stub-exchange.c
(gdb) p response
$1 = (SoupBuffer *) 0x1
(gdb) p status
$2 = 403
I'm not sure what a status of 403 from e2k_context_get() means, but it's
unlikely to mean "success" :-).
