I opened the statistics module for a repository containing tex files. On opening the tabs "Lines of code per type" or "Lines of test code", I get the following execption (unfortunately in German, it basically means that red has to be in range [0,255], but isn't):
System.ArgumentException: Der Wert -2147483648 ist für red ungültig. red muss größer als oder gleich 0 und kleiner als oder gleich 255 sein.
