Well the point is the registry is around 15 MB (I complained about this
size some time ago, I basically use only, org-capture and so gnorb and
then some label like TODO, DONE etc) and don't understand that size, so
I don't know how to really edit it in any reasonable way.

It is fortunately under mercurial version control (although mercurial
complains about its size), so I just reverted the file (in git speech
git reset --hard) to the last commit and everything now works.

The point is how can this be avoided, and how can I avoid so huge
registries 

I have 

gnus-registry-max-entries  10000


I can enhance it, but I still don't understand the need to write so many
entries.

Regards

Uwe
