Files from Attic reappear when merging a branch

[AS/EAB]

Hi 

I'm experiencing a problem with cvs update: 

When merging a branch on to main trunk, all the files from Attic
reappear in the merged module. The files in Attic where removed long
before the branch was created and therefore I cannot understand why they
should reappear at the merge. Is this a bug in CVS? 

The merge is done as follows: 
 
1. Check out the module on main trunk (cvs co). 
2. Merging the branch with a specific branch tag (cvs update -j <branch
tag>). 

At this point all the Attic-files reappear in the merged module. But
why? 

No files have been added/removed on main trunk, nor the branch, after
the branch was created. 

I would greatly appreciate any help on this matter. 

Kind regards
