Re: offlineimap crashes a lot

PII / 333 MHz, 192 MB ram, Debian stable, running KDE and far more bloat 
than one might expect on such an old system :)

Error messages follow. I'm not syncing huge messages at all ... I think 
it crashed today while downloading an offlineimap mailing list message; 
and it was only downloading maybe 3 or 4 messages in total.

I think the angelbase.com server is the one that is giving me trouble:

Trying 216.119.106.195...
Connected to mail.angelbase.com.
Escape character is '^]'.
* OK IMAP4rev1 SmarterMail

...I guess I didn't realize that "SmarterMail" (which I hate) has its 
own imap server. I guess that probably explains a lot. I've been 
planning to move angelbase.com to a different server, anyway.

I can't recall ever knowingly seeing a crash caused by the 
artoflivingla.org server:

Trying 66.175.37.201...
Connected to artoflivingla.org.
Escape character is '^]'.
* OK [CAPABILITY IMAP4rev1 UIDPLUS CHILDREN NAMESPACE 
THREAD=ORDEREDSUBJECT THREAD=REFERENCES SORT QUOTA IDLE ACL ACL2=UNION 
STARTTLS] Courier-IMAP ready. Copyright 1998-2005 Double Precision, 
Inc.  See COPYING for distribution information.

...I've seen some messages on this list that indicate that courier-imap 
is a pretty save bet. :)

Here's two ... I think they're pretty similar
