Created attachment 289699 [details, diff] patch to fix Exec= in xpdf.desktop Similar to bug 386941 ... XPDF only takes a single pdf file argument and it has to be a file though (can't be a URL), so %f needs to be used instead. I have attached a patch to the .desktop file; it seems to apply this it would be best to add the fixed .desktop file to the gentoo patchset ?
