[Dovecot] dovecot segfaults after upgrade
Using dovecot on debian oldstable (squeeze) with daily builded repository,
after an upgrade this morning, dovecot always shows the following error:
2013 Jun 10 11:07:22 mailstore imap(tblomenk): Fatal: master:
service(imap): child 3016 killed with signal 11 (core dumps disabled)
Jun 10 11:07:22 mailstore kernel: [ 1589.400741] imap[3016]: segfault at
7fffd9048ff8 ip 7f91417e2c3b sp 7fffd9049000 error 6 in
libdovecot.so.0.0.0[7f9141796000+bc000]
Please notice: I can reproduce the error by trying to access my mailbox
with alpine or mutt, while alpine only can access my inbox. If I try to
access my other folders, the error happens. Mutt always closes the
connection after trying to login. It is a little bit strange because with
a newer client like roundcube I can access all my folders successfully.
In all kernel error messages it seems that
error 6 in libdovecot.so.0.0.0[7f9141796000+bc000]
is always the same.
Also notice that dovecot is still running, it is just that you cannot
access other folders than your inbox with pine.
