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)
This is likely rather tricky to figure out / reproduce. I tried for a while with Evolution, but couldn't make it happen. Best would be if you could privately send me the output file of:
dovecot-sysreport --core /path/to/core/file
It will contain some bits of the user's emails though.
