问题
I have a project with with the following structure
^/project/trunk
^/project/branches/mybranch
where current HEAD is revision 1048. The branch was copied from trunk in r523. trunk has been merged to mybranch with the result being r1048. The mergeinfo on ^/project/branches/mybranch gives
/project/trunk:523-1047
and the mergeinfo of trunk has no record mentioning anything from ^/project/branches/mybranch. Actually in reality both trunk and branches also hold mergeinfos from branches parallel to mybranch but those mergeinfos appear as absolutely identical in both outputs.
Now I go into my working copy of trunk and try to issue
svn merge --reintegrate ^/project/branches/myproject
I get an error message that says:
svn: Reintegrate can only be used if revisions 523 through 1048 were previously merged from file:///home/svn/project/trunk to the reintegrate source, but this is not the case:
project/branches/mybranch/src
Missing ranges: /project/trunk/src:523-1047
That is weird because the mergeinfo on my branch folder tells me that 523-1047 have been correctly merged from trunk to branch. What is the deal with that subfolder? src is a directory that obviously exists in both trunk and branch.
I think that is where something is fishy. If I look into the mergeinfo of mybranch/src via svn pg svn:mergeinfo ^/project/branches/mybranch/src@HEAD I get nothing at all. If I look at the trunk/src however (svn pg svn:mergeinfo ^/project/trunk/src@HEAD) I get
/project/branches/mybranch/src:784
So it seems as though someone did a cherry-pick from branch to trunk there. However this does not appear in the trunk folder itself.
Is that where the trouble lies? And most importantly: how can I cure it??

Yes, exactly - merge subtree later always confuse reintegration
And most importantly: how can I cure it??
Remove mergeinfo from /project/trunk/src

Here is a very similar topic you might want to have a look at:
Reintegrate can only be used if revisions were previously merged URL to reintegrate the source
Especially this answer from Paul Whipp has helped me a lot when I encountered the same problem and didn't want to delete the mergeinfo, because this somehow sounded like a workaround and not a "real" fix.
In short: Try to merge the missing information manually for that specific file/ folder (just as svn suggests). Worked like a charm for me.
See Pauls answer for the corresponding code excamples, etc.
