Hi,
I'm using a recent git version to try to make a backup of my work email
(IMAP on server to maildir at home), using the following configuration:
MaildirStore local
Path ~/mailstore/
Trash Trash
IMAPStore SURFsara
Host imap.sara.nl
User paulm
Port 993
UseIMAPS yes
#CertificateFile ~/certificates/sara.crt
CertificateFile ~/certificates/terena-ssl.crt
#CertificateFile ~/certificates/usertrust.crt
#CertificateFile /etc/ssl/certs/AddTrust_External_Root.pem
Channel surfsara
Master :SURFsara:
Slave :local:surfsara
Expunge Slave
Sync PullNew PullFlags PullDelete
Create Slave
Pattern *
I get, however, a segfault:
melis@juggle ~ $ ~/software/isync-git/bin/mbsync surfsara

Running it under valgrind at least doesn't crash but there's an awful
lot of errors reported (including a lot in OpenSSL, which I find quite
scary). Some of the errors found in isync are:

Is this due to me using the latest git version and not the latest
released one? The reason I'm using git at all is that the release I
previously tried (1.0.6) I got segfaults as well, so figured I would
give the git version a try.
Thanks,
Paul
