Re: Exception on closing a window.

These are the warnings shown in the output console

'Project.exe' (Managed): Loaded 'C:\WINNT\assembly\GAC_32\mscorlib\2.0.0.0__b77a5c561934e089\mscorlib.dll', Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.

(Project.exe:3364): Gtk-WARNING **: ../../../gtk+/gtk/gtktreestore.c:824: Unable to convert from GdkColor to gchararray

A first chance exception of type 'System.FormatException' occurred in mscorlib.dll

The above exception is repeated several times

A first chance exception of type 'System.ArgumentException' occurred in gdk-sharp.dll

The above exception is also repeated several times

'Project.exe' (Managed): Loaded 'D:\Project_1\build\bin\Debug\nunit.framework.dll'

(Project.exe:3364): GdkPixbuf-WARNING **: GdkPixbufLoader finalized without calling gdk_pixbuf_loader_close() - this is not allowed. You must explicitly end the data stream to the loader before dropping the last reference.

The above Warning is also repeated several times

Now this exception seems the problem because the exception thrown while crashing comes from  glib-sharp.dll

(Project.exe:3364): GLib-GObject-CRITICAL **: g_type_free_instance: assertion `instance != NULL && instance->g_class != NULL' failed

Exception while disposing a Project.ModuleWindow in Gtk#

A first chance exception of type 'System.AccessViolationException' occurred in glib-sharp.dll

The program '[3364] Project.exe: Managed' has exited with code 0 (0x0).

Application crashes with this message.
