Crash on rotation of "Pattern along Path"

[Lucas Chamorro]

Hi

I'm having this crash precisely when I rotate the uppermost pattern along path (the ladder thing closest to the center molecule). Any angle does it, and it happens when I release the mouse button (the pattern rotates, but the program crashes after).
I've reproduced this 4 out of 4 times I've tried, with the file I'm attaching.
I'm running Inkscape version "0.92.0 r" in Arch Linux.

I'll try to provide any additional info you may need.

Cheers.

Seems to occurs when both Snap to path and Snap cusp nodes are active in the snap toolbar.
