Public bug reported:
When viewing a certain PDF (which I unfortunately can't share) using
evince, a see a crash in libpoppler90. It's a NULL pointer dereference
in TextSelectionPainter::hasGlyphLessFont(), because in this certain
PDF, for whatever reason, sel->word->getFontName(0) may return NULL.
Attached you'll find a proposed patch increasing the robustness in this
case.
Cheers,
Enrik
