Hi, When I receive an SVG attachment, it first makes emacs freeze and then crash. It might not be a problem of notmuch but a helper application, but I don't know how to debug it; so maybe someone here can help me. Any ideas? Btw. it seems that the general problem is the the message mode tries to process attachments. For example when I receive a large .tgz file, the message mode in notmuch tries to decompress and parse the file, which may take a while. Thanks, Sebastian
