OK, I found the causo of this problem: I tried to hack a little on
account-piecharts.scm directly in
/usr/local/share/gnucash/guile-modules/gnucash/report/standard-reports/.
This left me with account-piecharts.scm~ (the backup file) in the
standard-reports directory.

Obviously there is some for-each file in directory logic there which
got screwed up by the backup file. It might be a good idea to
explicitly list the files to load somewhere, wouldn't it?
