Memory consumption is increasing with each hide/show cycle of the layer containing the embedded image, though with above images in the range of 5/10 MB when hiding and 10/30 MB when showing the layer. Memory is not released after deleting the embedding image or closing the document window.

repeated console messages (with varying size depending on image):
** (inkscape-bin:56339): WARNING **: GC Warning: Repeated allocation of very large block (appr. size 12328960):
 May lead to memory leak and poor performance.
