--- Comment #7 from Lemmiwinks <andylem...@googlemail.com> --- Which graphics driver are you using? Are we all using nouveau? I renamed kmail2rc in .~/.config/ to kmail2rc.old and got the following error when starting kmail: bash-4.3$ kmail "Tag 'a' is not defined in message {<__kuit_internal_top__>KMail has many powerful features that are described in th...}." "Tag 'br' is not defined in message {<__kuit_internal_top__>Thank you,<br/>The KMail Team</__kuit_internal_top__>}." this does not work on a KActionCollection containing actions!
