CtxMenu.dll - Windows Explorer has encountered a problem

I had been suffering for months with "Windows Explorer has encountered a problem ....." but could not find the cause, nor could I relate this to any particular action.
On the first scan with ShellExView I found one extension with no Company name against it - CtxMenu. I disabled this and 'hey presto' my problem has gone away. I have no idea which program has installed this module but I certainly have not lost any functionality in any of the software that I use.
Thank you for making this very useful utility availabe.

The details of the shell extension that might cause the problem:

Shell Extension Name:	Image Converter context menu
Filename:	CtxMenu.dll
Description:	CtxMenu

File Version:	1, 5, 0, 3300
CLSID:	{C6643EC0-49AC-4c15-A455-04104DB900A9}
