[Robert Ancell (robert-ancell)]

Can you reproduce this problem? Can you run evolution from the terminal and see what output is printed?

It appears what might be happening is the email doesn't contain valid UTF-8, and dbus/gvariant doesn't handle this case.

[Fabien Tassin (fta)]

I can sure reproduce the crash. it happened to me a dozen times already this month.
It's always with a spam (i get lots of them).

I'm now capturing the outputs. I will update the bug once I have something.

[Robert Ancell (robert-ancell)]

Note, you should be able to workaround this problem by going to Edit>Plugins, then select the Mail Notification plugin, and disable "Generate a D-Bus message" in the configuration tab.

[Sebastien Bacher (seb128)]

It's somewhat similar to https://bugzilla.gnome.org/show_bug.cgi?id=635825 but as it was writen in previous comment it seems somewhat non valid utf-8 strings are used there

[Sebastien Bacher (seb128)]

Could you maybe ping the #evolution guys on IRC or open the bug on bugzilla.gnome.org?

[Sebastien Bacher (seb128)]

Unassigning from ubuntu-desktop to avoid spamming the list with bug emails, setting to low since that option is not on in the default installation

[Fabien Tassin (fta)]

Still there.
