Ipe 7.2.30 memory leak when using graphicx \includegraphics

[lkschu]

System

• Ipe 7.2.30
• Arch Linux

Steps to reproduce

• New document with \usepackage{graphicx} in the latex preamble
• Make a paragraph with \includegraphics{path/to/your/image}. The image should be a PNG or JPG (not PDF) and should have a decent size, like 4000px x 4000px, so the leak is faster noticeable. It will, however, work with any size.
• Now add a new page and jump back and forth, alternatively save the document multiple times. RAM consumption will increase rapidly (100s of MB per step for a larger image)
• The memory is only released when Ipe is closed or killed. Switching to another document does not free the allocated memory
• The huge amount of allocated memory also makes Ipe sluggish when scrolling through pages

EDIT: Moving the page by scrolling with the mouse wheel or by pressing the middle mouse button also causes the memory leak if there is a graphic with \includegraphics{} on the page.
