[Evolution-hackers] Regular core dumps in Evo 3.6.0

[Paul Smith <paul mad-scientist net>]

Hi all; I'm using Evolution 3.6.0 in GNU/Linux Mint 14 with Cinnamon as
the desktop.

I'm using IMAP+ to access 3 different IMAP accounts: two Google accounts
and one "normal" IMAP (from my ISP; I think using Dovecot).

I'm finding that I'm getting core dumps in Evolution fairly often: once
every couple of days (from SIGTRAP?), and I can also get Evo to dump
core (with SIGSEGV) every time I visit a particular email (received
through one of the Google accounts, but the dump appears to happen in
the display engine so the backend is probably not relevant).

I realize that I'm not using the latest (it really bugs me how the
standard distributions never seem to bother to package the Gnome point
releases :-/).  Is it worthwhile sending along backtraces (I've
installed the evolution-dbg packages at least)?

Should I just build my own latest versions?  In the past (but this was
Gnome 2.x) I've had problems with this: confusing dbus between the
different installations, etc.  Maybe this is more cleanly supported now?

Cheers!


Just FYI, I'll include the stack trace of the reproducible core, on a
particular email; unfortunately the libcamel library doesn't seem to
have a debug package available:
