Comment 1 for bug 1674998

Confirmed on Xubuntu 16.04, Inkscape 0.91, lp:inkscape/0.92.x rev. 15420 and lp:inkscape rev. 15658.

Seems to occur when the Text & Fonts dialog is open before you start typing the first text element of the session. If you first enter some text and then open the dialog, everything seems ok.
