Crashing after copy paste mesh gradient, exporting damaged pdf

Summary:

Copying and pasting elements (that have mesh gradients) results in crash

Subsequent PDF export results in damaged pdf - cannot be opened.

(I previously had similar problems with PDF exports, most of the works with faulty PDFs included gradients)

crash log from inkscape:
