Is your repository public?  If not, could you give a sketch of the project
history, for example by running

 $ git log --oneline --name-status

from a successful (non-stdlayout) clone?

Redirecting discussion to the git mailing list; maybe someone there will
have other ideas for debugging.

Thanks for reporting,

Since your trunk directory is called "trunc" rather than "trunk", it seems
stdlayout is not appropriate for the import.

There is also a tag named "trunc".  Not sure how that will work out. :(

Anyway, hopefully that information can help interested people to reproduce
this problem, document it, and make it fail with a better error message.

For your import, perhaps

	--trunk=<trunk dir> \
	--tags=<tags dir>

would give better results?

If this is a one-time conversion (i.e., it will not need to be updated with
later changes from svn), then you might also find some of the methods
described in

 http://thread.gmane.org/gmane.comp.version-control.git/158940/focus=159054

helpful (especially use of "git filter-branch" to extract subdirectories
from a simple whole-tree import).

Hope that helps,
Jonathan
