Crashes QGIS or corrupts data changed from No to Yes

#3 Updated by Radim Blazek over 11 years ago

Status changed from Open to Feedback

Works for me on Debian and Win XP.

It seems to crash in QgsOptionsDialogBase::restoreOptionsBaseUi where I see some really dangerous code:

int curIndx = settings.value( QString( "/Windows/%1/tab" ).arg( mOptsKey ), 0 ).toInt();
if ( !mOptStackedWidget->widget( curIndx )->isEnabled()

It means that if in settings was stored higher index than how many widgets are present, mOptStackedWidget->widget( curIndx ) returns null and it must crash.

Could you please try to open regular local raster (tif), open its properties, select "General" widget (tab), close properties, try to open properties of wms layer.
