Comment 6 for bug 510618

in recent builds the entry in the 'Undo' history when opening a document in second (new) window is no longer related to the connector code but now (r9410) says

> Text: Change line-height

This bug seems to be triggered when the controls bars for the individual tools are created or packed for a new document window (src/widgets/toolbox.cpp) because I never see it when the opened document reuses the current window (of a new from template, unchanged document).
