Oscope and Logic Analyzer

When I press the Expand key in the scope and
in the logic analyzer I get the following warning:

Warning: QWidget::setMinimumSize: (plotDisplay/PlotDisplay) Negative sizes (-6,143) are not possible (:0, )

Also in the files:
DataLaWidget.ui
DataWidget.ui

in some QLineEdit, StyleSheet contains an error:

background-color:# *Invalid Style Sheet*

which gives these warnings:

Warning: Could not parse stylesheet of object QLineEdit(0x28ca190, name = "channel3") (:0, )

Thanks, solved at trunk Rev 1549 and 1.0.0 Rev 1261.
