Title:
  evolution crashed with SIGSEGV in efh_text_plain()

Status in “evolution” package in Ubuntu:
  New

Bug description:
  Hi there,

  I'm running 64bit Ubuntu 11.10 Kernel 3.0.0-13 and Evolution evolution:
    Installiert: 3.2.1-0ubuntu1
    Kandidat: 3.2.1-0ubuntu1
    Versionstabelle:
   *** 3.2.1-0ubuntu1 0
          500 http://at.archive.ubuntu.com/ubuntu/ oneiric-updates/main amd64 Packages
          100 /var/lib/dpkg/status
       3.2.0-0ubuntu2 0
          500 http://at.archive.ubuntu.com/ubuntu/ oneiric/main amd64 Packages

  The installation is only a few days old (complete an new) and I've set
  up Evolution as my mail program. Using gmail, google contacts and
  google calender, it is just the app of choice.

  When I try to view certain emails in evolution (of my gmail account), Evolution just crashes with a segmentation fault (Speicherzugriffsfehler).
  I see very shortly before the crash some error message like:
  Fehler beim Überprüfen der Signatur (translates to Error checking signature)
  security library: improperly formatted DER-encoded... (can't read the rest, gone to quickly)

  dmesg says:
  [ 2644.539233] evolution[5546]: segfault at 30 ip 00007f003cf1a368 sp 00007f002f0eb780 error 4 in libevolution-mail.so.0.0.0[7f003ce9f000+ca000]

  This seems to be linked to viewing certain mails of certain senders. I
  can access most mails, but it seems that of a few senders I can only
  see a few wheras most mails of these senders trigger the crash. It
  seems that they have in common that they use e-mail certificates
  (signed e-mails), but I can not 100% confirm this.

  I think since the update to mbox, I might have that problem but I'm
  not sure.

  Any help appreciated. It's my first bug report, so please be patient
  with me... :-)

  Cheers

  Helge
