Quit anyway? (y or n) y

	Hi,
install debug info packages for evolution-data-server and evolution,
then run evolution under gdb:
   $ gdb evolution --ex r
and reproduce the crash there. Once the gdb prompt stops due to the
crash (SIGSEGV) run these gdb commands:
   (gdb) bt
   (gdb) q
and for a quit prompt answer 'yes'. This will print a backtrace where
the evolution crashed.

The thing is that the tnef attachments require a tnef plugin to be
compiled. If you've it there, then it can also crash inside the plugin
and/or the library the plugin uses.
	Bye,
	Milan
