Runtime error for atibtmon.exe when disconnecting AC power cord

Everytime I disconnect my AC power cord Windows 8 shows a Erro Dialog:

Runtime Error!

Program: C:\WINDOWS\system32\atibtmon.exe

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information.

Anyone having the same problem?
Any hotfix for this?

Computer: DELL XPS Studio 16

Answer

Unchecking the "Vari Bright" option in the ATI Catalyst Control Center resolved the issue for me as well.  It seems this option dims the brightness of the display when unplugged; however, I believe Windows also does this (or, at least it does on my Dell XPS 16).  Perhaps two programs attempting to essentially do the same thing are the cause of the atibtmon issue?
