Comment 1 lnxusr 2018-12-14 18:56:15 UTC

This happens on both my IMAP and local folders, although the only local folder I have is the trash, trying to open any email in it results in a segfault as well.

Composing and send email works, as does receiving from my IMAP server.  Any email I try to open segfaults the damn thing.

Comment 2 blackfireburn 2018-12-15 20:41:28 UTC

I can confirm the same behaviour on the same versions as OP

Comment 3 Wolfgang Bauer 2018-12-15 23:15:54 UTC

The crash looks like the one in bug#401419.

The last comment there states that this apparently only happen if you disable the preview pane in the settings.
Activating it again should fix the crashes it seems.
