Your project uses the gb.gui component. So, when running on Cinnamon desktop as you are, it would use GTK. And, when running on 
the KDE desktop as I do, it would use Qt.

As a test, I switched to using the gb.gtk3 component in the project instead of gb.gui. After launching Lazarus in multi-window 
mode, I could no longer bring up the WinPin UI by clicking on the sys-tray icon. And, upon closing Lazarus, I got the same error 
as you (with the exception of "serial 2601"):
~~~
(WinPin:11659): Gdk-ERROR **: 12:06:09.436: The program 'WinPin' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
   (Details: serial 2601 error_code 3 request_code 20 (core protocol) minor_code 0)
   (Note to programmers: normally, X errors are reported asynchronously;
    that is, you will receive the error a while after causing it.
    To debug your program, run it with the GDK_SYNCHRONIZE environment
    variable to change this behavior. You can then get a meaningful
    backtrace from your debugger if you break on the gdk_x_error() function.)
~~~

So, it's a GTK issue, or an issue with the Gambas GTK interface.
