ristretto crashed with SIGSEGV in rstto_main_window_save_geometry_timer_destroy()

[Chris Guiver]

Note: launchpad suggested https://bugs.launchpad.net/ubuntu/+source/ristretto/+bug/1815486 but it related to an older version packaged for xenial/bionic however it could be same issue

Ubuntu 20.04 LTS QA-test (live using latest daily)
dell [optiplex] 755 (c2d-e6850, 5gb, amd/ati radeon rv516/x1300/x1550)

Opening files found on local hdd using install apps; in this case it was a file that started playing & I closed app (ristretto) to move to next file & moments later crash report appeared.

It's likely the crash was on exit; I'd moved my attention to thunar looking for next (different type) file to open using an installed app, so had mentally switched away from ristretto & didn't expect the apport window to appear.

Amendment: I assumed it was parole that crashed on WAV file; only just realized it was probably PNG (saved screendump).. There was a delay I think before I noticed apport

I cannot reproduce this bug in 0.12.3, possibly it got fixed somewhere along the way, although rstto_main_window_save_geometry_timer_destroy() hasn't been touched since its inception.
