You can also dump exception more detailed exception info: include exception stack, it will show line numbers and also all inner exceptions -- recursively. Dump it in some text file, then present sufficient code sample and indicate in which line(s) exception was raised/handled. Post both dump and code.

So far, you did not even report exception Message (what you show does not include Message).
How can you hope someone point out your problem without this data?
See System.Exception for more detail.

What is calling the constructor? what code are you using? Without that, we really can't help.

That is not fired from his code. That much is evident from the call stack.

Even i wanted the exact line number where of the exception so I placed try/catch blocks through out my code but somehow the exception is only caught in the main program.cs. Strangely i am unable to reproduce the error on my machine its happening only in production. I even included the/pdb(debug symbols) file in production build to get the line number but no luck. As nishant suggested i am trying to check if the code is disposing all the image objects properly but so far i dont find any problem there. Is there any way i can get the line number

i finally got line number the error is thrown when i am trying to open a form
FromToSPG fromToSpg = new FromToSPG(FromToSPG.FromToSPGMode.StartClip, articleMetaData, allkeywords, e.Zone, pageCollection, false, toolOptions.BatchNumber, null);
if (fromToSpg.ShowDialog() == DialogResult.OK)
{//do something

Most likely cause is that either width or height is negative.

[Update]

Okay, having read your update it seems to me that you are not releasing unused GDI handles. The error you get is kinda arbitrary (and not from your user code). I believe that when Windows tries to repaint the app icon, coincidentally it hits the GDI handle limit, which results in some failed GDI calls, so by the time Icon.ToBitmap calls the Bitmap ctor, many or all the arguments are invalid (you cannot see this unless you have the public symbols for debugging).

So your next step is to double check if you are properly disposing off all your image objects after they are done with.
