<snip/>Hi Benoît, meanwhile I think that the problem is not about how to include an image into the pdftitle field, but that the image clause has been included _accidentally_ into the pdftitle: the image clause is only targeted at the document's title, but not for the pdftitle field. Correct? Thus I have created a somewhat clumsy hotfix [1]: computing a separate XSL variable "pdftitle" based on the contents of the previously computed XSL variable "title", stripping off any image clause. Detecting and stripping off an embedded image clause is somewhat fragile: if you ever change the structure of the image clause in "title" determination, "pdftitle" computation would need to get adapted. At least both possible settings of configuration parameter imagedata.file.check are taken into account, I used the "pdfinfo" command for inspecting the resulting pdftitle value. If you are developing a more elegant respectively robust way for fixing the problem, let me know, otherwise I would release a new Debian dblatex release with my hotfix soon, as the BTS report is quite urgent due to the FTBFS: "Serious (policy violations or makes package unfit for release)" [1]

Don't try to include a title image in the pdftitle field of TeX package
hyperref, as this field doesn't support images.
