Dear list, at some point my document started throwing an error ! error: (nodes): trying to delete an attribute reference of a non attribute node I managed to extract a minimal example which shows the error (below). However, the error only occurs when the filename of the document contains a hyphen! When I save the document as `test-error.tex' the error comes up, when I save it as `testerror.tex' it typesets smoothly. Unfortunately, I currently cannot update to latest beta because I have an important document where I cannot afford any regressions.
