Testing patch with Inkscape 0.48+devel r9686 on OS X 10.5.8 (poppler 0.12.4):
- Using the test case from bug #605872 (comment #6), Inkscape 0.48+devel r9686+patch2 opens the PDF file without crash, and after saving it as Inkscape SVG, the file can be reopened without error messages and renders correctly in Inkscape AFAICT.
- Command-line invocation to convert the PDF file not yet tested.
See also this message on inkscape-devel which has a list of potentially related reports I had compiled earlier (see item 3b):
@JazzyNico - can you confirm this on linux/win32?
