gwenview in tmux in konsole on plasma 5 is almost entirely silent on the terminal (which is great) except for this warning: mCurrentMainPageId == 'StartMainPageId' it happens after I start gwenview and press ctrl+Q to exit it immediately.
One should note that gwenview is more noisy on the terminal in Xfce and JWM via startx on a new user.
The warning is nothing serious, but I worked on a (trivial) patch for this end of last year anyway. I guess I should free some time to post it for review eventually…
STR: Close Gwenview from start page. Introduced with 528d88408188 in 2013. Fixed with 602db1bcbe08, i.e. my patch isn't even necessary anymore.
