In plugingui.cc insert tab character somewhere in:
<code c++>
lbl_version->setText(".::. v" VERSION "  .::.  http://www.drumgizmo.org  .::.  GPLv3 .::.");
</code>

Now the ''while(true)'' in void LineEdit::repaintEvent(RepaintEvent *repaintEvent) never termninates because of the 
<code c++>
	while(true)
	{
		int textWidth = font.textWidth(visibleText);
		if(textWidth <= (w - BORDER - 4 + 3))
		{
			break;
		}

</code>

The if conditional never seems to be activated...
