PDF file that makes Okular crash.

SUMMARY

Okular crashes when viewing a certain page of a PDF I have.  I used pdftk to extract the page in question to a separate PDF file; having Okular view the file with this single-page PDF also makes it crash.

STEPS TO REPRODUCE
1. Open the attached foo.pdf.

OBSERVED RESULT

Okular crashes with the following error:

terminate called after throwing an instance of 'std::length_error'
  what():  vector::_M_default_append

EXPECTED RESULT

Okular should display the file without crashing.  (Other PDF viewers, such as Evince, are able to do so.)

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: 
KDE Plasma Version: 6.5.5 
KDE Frameworks Version: 6.22.0
Qt Version: 6.10.2

ADDITIONAL INFORMATION

See attached backtrace.
