I always get the following error when opening a source-file: “The file ‘/home/xyz/…’ could not be opened. Error while loading style efault” and the stacktrace prints the following lines:

System.IO.IOException: Error while loading style efault —> System.TypeInitializationException: An exception was thrown by the type initializer for System.Drawing.KnownColors —> System.TypeInitializationException: An exception was thrown by the type initializer for System.Drawing.GDIPlus —> System.DllNotFoundException: /usr/local/lib/libgdiplus.so
