+Short answer: install @t{nspluginwrapper}. Longer answer: @t{mu} comes
+with @t{msg2pdf}, which is a program used to convert the messages to
+pdf, and which depends on WebKit, which in some cases needs
+@t{nspluginwrapper} and it waits for a long time if it's not there. So,
+installing @t{nspluginwrapper} prevents that.
