mutt freezes some times when accessing imap folders or messages

[b.macdonald]

Mutt sometimes hangs when fetching a message, or opening a folder while fetching headers from an imap server. The imap server is Cyrus IMAP4 2.2.12-Invoca-RPM-2.2.12-8.1.RHEL4. This happens also with mutt 1.5.12 on one machine, as well as with mutt 1.5.13. This happens occasionally, not that often, but enough to be frustrating since mutt has to be restarted and changes to the mail folder are lost. Several times a day. Mutt won't respond except for ctl-Z to stop it, then the mutt process must be killed. In one case I collected a debug log from mutt -d, which showed that mutt has frozen part way through downloading an attachment. No error messages are given, the log simply stops part way through outputing the attachment to the log file.

Well I'm not sure this is mutt or cyrus imapd but not sure how to tell the difference and the imap server is not accessible to me.

I also submitted to Debian, bug #431258

[brendan]

This may have been fixed in 1.5.17. Can you reproduce with that version?

[b.macdonald]

Hi Brendan, sorry but it still happens with 1.5.17. I'm using Debian packages, and the latest is 1.5.17. Tried it on two machines and both still freeze. One my laptop from home over a broadband link, the other logged in to my desktop at work, and running mutt on that. If there is anything I can do to help let me know.

I am also seeing this, RHEL4 stock cyrus Cyrus IMAP server. Mutt both RHEL4 built in 1.4.1i and a hand built 1.5.17

Occasionally the client will just lock up for 5-10 mins. then it will drop the connection. Cyrus does not see any commands durning this,

a0097 OK Completed (0.000 sec)

is what the cyrus log provides which is the last command issued was completed OK.

I don't see an option -d to debug mutt, is this something i am missing at compile time?

Here is .muttdebug for -d 2 w/ the above 1.5.17 version w/ --enable-debug

Are you using ssl or gnutls? This may be the same bug as #3074. I've committed a possible fix (at least for gnutls) there. If you could try it out, that would be great.

[Bruce MacDonald]

Hi, I haven't grabbed the code yet (I usually just use the latest
ubuntu package), but when I turn off ssl and gnutls the problem still
occurs, although perhaps less frequently. Bruce
