Yeah, the crash is in file-pdf-load, and the stack trace is from gimp.

you can start gimp like this:

  GIMP_PLUGIN_DEBUG=file-pdf-load Gimp North_by_Northwest__1959_.pdf

and then attach a gdb to the process when gimp halts the execution of
the plugin on startup.

which gives this stacktrace after the crash:

[...]

So it seems that this is a) something in libpoppler, maybe related to
getting thumbnails, and b) might be related to a unusual color space
specification in this specific PDF.
