second image that causes a crash
I can confirm the bug with the attached image “second image that causes a
crash”.
I can reliably reproduce the bug by opening the image (the image is initially
resized to fit the available space) and then clicking the 100%-zoom button.
Strangely, the crash does not occour if I zoom in _slowly_ step-by-step using
the zoom-in button or Ctrl+Scroll-Wheel. If I zoom in fast (e.g. by clicking
the zoom-in button rapidly), the crash occurs again.

Sorry for the incomplete debug information. It is a bit cumbersome to install
debug information on Arch Linux – too cumbersome for me at the moment.
