[poppler] [PATCH] Tagged-PDF: Fix parsing of attached element attributes

[Adrian Perez de Castro]

The wrong object was used as attribute dictionary, which caused
a segmentation fault when parsing PDF files in which the structure
elements included attributes attached to them. This patch fixes the
issue.

Thanks to Joanmarie Diggs <jdiggs at igalia.com> for helping in
debugging the problem.
