SIGSEGV - Segmentation fault on start

1)The program don’t start. It return a SIGSEGV – Segmentation fault error. I correct add a int cast to variable knob_width in file Fader.cpp. I change the line 439 of file Fader.cpp:

before

painter.drawPixmap(QRect((width() – knob_width) / 2, knob_y – knob_height, knob_width, knob_height), m_knob, QRect(0, 0, knob_width, knob_height));

after

painter.drawPixmap(QRect((width() – (int)knob_width) / 2, knob_y – knob_height, knob_width, knob_height), m_knob, QRect(0, 0, knob_width, knob_height));

2)The Add Plugin’s window don’t load plugin’s list. I change in backend/effects.cpp file the line 57

before

m_ladspaPathVect << sLadspaPath.c_str();

after

m_ladspaPathVect << sPath.c_str();

I also add this istructions in the LadspaFXSelector class costructor for greater readability

QPalette defaultPalette; defaultPalette.setColor(QPalette::Base, QColor(88, 94, 112)); defaultPalette.setColor(QPalette::AlternateBase, QColor(138, 144, 162)); m_pGroupsListView->setPalette(defaultPalette);
m_pPluginsListBox->setPalette(defaultPalette);
