It is only partially related to text, I will file a bug report with
the example files.

I wonder whether a hybrid approach is possible, as I don't think one
needs to edit the PDF image in Ipe: For the display on canvas one
could quickly (upon import) calculate a rasterized "thumbnail" of the
PDF, which in the final PDF output is replaced by the actual scalable
image. This way one wouldn't need a PDF interpreter. But I can of
course not judge whether this needs large changes in Ipe.

Can't poppler-qt4 provide all the necessary bits to do that easily?
Cheers,
Frank
