I can confirm that this looks like an import problem.
(e.g see svn log -v -r33:78 https://avogadro.svn.sourceforge.net/svnroot/avogadro)

I did my analysis on the file /trunk/avogadro.pro, because the error
happens really early in the history so could just import up to revision 76
to see what goes wrong. (The file gets never deleted in the import, as it
should be!)



trunk/avogadro.pro is added here:

    ------------------------------------------------------------------------
    r33 | dcurtis3 | 2006-08-21 07:34:10 +0200 (Mon, 21 Aug 2006) | 3 lines
    Changed paths:
       A /trunk/avogadro.pro

    Does a recursive build.


Here the refactoring starts (a new directory not tracked by git is added):
    ------------------------------------------------------------------------
    r66 | dcurtis3 | 2007-01-03 06:42:45 +0100 (Wed, 03 Jan 2007) | 3 lines
    Changed paths:
       A /avogadro

    Making room for libavogadro.


/branches is moved to /avogadro/branches
    ------------------------------------------------------------------------
    r67 | dcurtis3 | 2007-01-03 06:47:11 +0100 (Wed, 03 Jan 2007) | 3 lines
    Changed paths:
       A /avogadro/branches (from /branches:66)
       D /branches

    Making room for libavogadro




ERROR HAPPENS HERE:
====================

/trunk and /tags are moved, too.
(/trunk/avogadro.pro becomes /avogadro/trunk/avogadro.pro):
    ------------------------------------------------------------------------
    r68 | dcurtis3 | 2007-01-03 06:47:34 +0100 (Wed, 03 Jan 2007) | 3 lines
    Changed paths:
       A /avogadro/tags (from /tags:66)
       A /avogadro/trunk (from /trunk:66)
       D /tags
       D /trunk

    Making room for libavogadro.

The above delete/move of trunk isn't recorded anywhere in the git svn import.
'git-svn find-rev r66' doesn't produce any output!
And later git-svn thinks that /trunk and all its files are still there, so
e.g. /trunk/avogadro.pro stays in the repo forever.


-Peter

This is just for consistency here and for anyone interested in further
analyses.

Here is the rest of the import analyses I've done. Look how "interesting" the
repo is and how many times the files are moved.




/libavogadro is added

Create /libavogadro/{trunk,branches,tags} and move anything below the
former /libavogadro into /libavogadro/trunk

    Now uses libavogadro.  Starting to think we should package this a
    little different.

    Moving things around.  Conforming to a more KDE-like layout in SVN.
