An error inside a klammer is reported at your document; the image search path

Assembled from development commit 632297b7657a. Since 1b00738: when something
goes wrong while a klammer is being applied, the report begins with the
line of your document that applied it, then lists the klammers being
applied and where inside the klammer set the fault was raised; the
Python binding's line and column are the application's too. The default
image search path is the document's directory, imgsrc beside it and
../imgsrc, and a not-found report shows exactly those.
