[Evolution] Bug#585953: Narrowing of this Problem

[Yusuf iskenderoglu]

I wanted to note that of my two systems running debian unstable (daily
upgrades) on i386 and amd64, only the 32-bit version of evolution
crashes when showing emails with text/calendar attachments.

The trace that is being generated shows, that itip_format() is causing
the problem.

Disabling the "ITIP Formatter" plugin on the 32-bit system results in
stability, however with reduced functionality regarding event
notification mails (the interface is no longer displayed, the mail is
interpreted as text).

Regards,
Yusuf.
