Interestingly, after restarting the server the problem went away.
I left work and turned off the computer with a troubled mind and the next 
morning the error was gone!
I just left it at that. Obviously this was irrational and caused by some 
bug somewhere (most likely caused by the complexity of my site in some 
strange way).
Now it works and I have not seen it since. Unfortunatly I don't have time 
enough on my project to look into it.

Thank you for your help, Peter
