Dear CCPNers,

I have been seeing this error message often in new projects, old projects, etc.etc. Sometimes it correlates with opening a new spectrum, sometimes it will appear to affect spectra I have had open in the project for some time. If I delete the new spectrum I have just opened, the project appears to perform normally. Sometimes if I reprocess the data and open it in analysis again, it read it ok, sometimes not. I cannot seem to find the correlation.

I have the latest updates to analysis and am running on:

OSX 10.6.8, 2.8 GHz Mac Pro

 Below is an example traceback.
