Bug 791397 - Gimp import multi page PDF only imports first page.
Poppler and poppler-data are now hard dependencies. PDF is a common-enough format nowadays that import support is likely considered as a granted feature by everyone. Moreover the current fallback to the PostScript plug-in for PDF support just gives a degraded experience with less features (and probably a lot of bugs since basically nobody uses this code). Poppler-data is also considered mandatory because non-western language support should never be considered an "option". People using non-western languages are not second class citizens and therefore if we say that PDF import is now a hard feature, it should also include PDF using CJK or Cyrillic languages.
