        Hi,
I guess, and only guess, that the .pdf.p7m is shown in its source form,
like a plain text message, and as it's quite large (several megabytes?)
then preprocessing of the data and WebKitGTK+ rendering takes a long
time. You can work with the application, only the preview panel is
frozen and doesn't update, right? You may also see that one of
WebKitWebProcess processes is using a lot of CPU. There is already
filled a bug about this [1].

the sender's side, sending large PDF file incorrectly attached into the
message. I admit I didn't see the message itself, whose structure can
prove that I'm wrong.

A workaround is to disable the preview (Ctrl+M), or by running
evolution as 'evolution --disable-preview', and then do something with
the message. Eventually wait until the rendering is finished and only
then do something with the message. How long it'll take depends on the
message size.
        Bye,
