Windows Explorer appcrash on startup

At every startup now, Windows explorer gets an appcrash in module ntdll.dll
I can however start Task manager.
Using TM, I can start various programs such as Firefox, Thunderbird etc.
It now seems that if I maximize Task Manager, I can start Windows
explorer (using TM) and WE will come up without crashing.
However, if the desktop is (or rather, would be) visible upon an
attempted start of WE, it will crash.

When trying to start explorer using TM, the crash will be in various
modules, not only ntdll.dll.

So, my understanding is that WE crashes upon startup because of
something that is visible on the desktop.
But there are only various icons, and nothing special...

Anyone with thought/ideas on this?

Look at the more information and see if you can narrow it down and remove
the faulting program?

Things are getting clearer (in a way...)
There are other problems that probably have the same root cause.

I have a graphic program that opens image files.
If in the open menu I have the "icon" view selected, the program crashes.
(it is all jpeg:s)
If I have the "list" view selected the program opens the file OK.
So, the problem has something to do with graphic thumbnails/icons.

I have recently installed a new version of DIVX.
I removed it, but the problem remains...

Now, I have learned to live with/circumvent the problem since I seem to
understand it, but I must eventually find a solution.

My understanding is that programs that crash are badly written.
The crash occurs mostly in ntdll.dll which is written by Microsoft.
So, Ms ought to fix this, or am I getting it wrong?

It might of course be that ntdll.dll is being fed bad input data, but a
good program tries to validate its inputdata in order not to crash.
(At least that is the way I try to do things myself..)

ntdll.dll was the module that crashed you have to scroll down a little in
the box to see the faulting .exe or .dll file and then find that in program
files and remove the program and see if the problem goes away. Then either
live without that program that was causing the faults or get an updated
version.

Hope this help, Rich

I'm not sure I understand...

As I understand it Explorer.exe calls ntdll which crashes.
Or is it that ntdll in its turn has called some other code that crashes?
