Hi Folks,
I'm seeing imapd crash when an evolution user accesses her primary mailbox.
She can see the mailbox perfectly well using thunderbird or Apple
Mail on an iPad; just not from her evolution instance.
Version is 2.4.1-4 (7d8c0e5759)
The error is an assertion failure:
Panic: file istream-header-filter.c: line 665
(i_stream_header_filter_snapshot_free): assertion failed:
(snapshot->mstream->snapshot_pending)
I'm running on Debian unstable in an LXC container, using the Debian
packaged version of dovecot. Filesystem for INBOX (mbox format) is
XFS; home directories are mounted via NFS.
The backtrace in gdb is:
