Sorry, no luck with the new patch But I found a very good lead!
The problem seems to be tied tightly to the line wrapping on the WYSIWYM screen WHILE LOADING IMAGES. * If I maximize the LyX window before opening the document, the bug can * Choosing Danish language simply change the size of a loading figure by having a different length of displayed status messages. A loading images HAS to be visible on screen while loading to see the bug. Try out the attached minimal offending document. It fails in English now due to a change in line length. Be sure to not maximize your LyX window and deactivate raster font rescaling in LyX in order for the bug to be seen. I use the default LyX windows size. The included image does not have to be included. Claus Hindsgaul
