Package: gthumb
Version: 3:3.4.3-2
Severity: important

I used the mouse wheel when viewing images (and videos), and gthumb
crashed.

Core was generated by `gthumb .'.
Program terminated with signal SIGSEGV, Segmentation fault.
#0  0x00007ff409a16d78 in preloader_load_ready_cb (
    source_object=<optimized out>, result=0x5602cf55dac0, 
    user_data=0x5602cf53a990) at gth-image-viewer-page.c:1044

I've attached a full backtrace.

This is reproducible. This second time, I get:

[Current thread is 1 (Thread 0x7fdb330c0a00 (LWP 24199))]

Each time, it seems that the crash occurs when one reaches a video.

When an upstream bug is marked as obsolete, this does not mean that
it is fixed upstream.

Anyway, it appears that this upstream bug was actually fixed in 2018
and should have been closed as fixed. And I haven't seen any crash
for some time, and I can't reproduce the crash now. So I'm closing
the bug.
