Yes, that could be it. The widget is rendered using CSS and the
Adwaita CSS rule references "process-working-symbolic" as the
icon, and that icon is only shipped in SVG format AFAICT.
(1) sorry, I've been in write-only mode for a long while now. That's why
we've apparently arrived at nearly the same conclusions thus far,
duplicating (triplicating?) our efforts. That said, I'm glad we did
arrive at the same ideas.
(2) A number of surprises:
(2a) p2v already spells out icewm[-lite] as a depencency, just not when
the VM boot disk image / ISO image is based on Fedora (more precisely:
for SUSE). When building on Fedora, the WM included is Metacity instead
(and the launch script starts metacity vs. icewm accordingly.)
(2b) There is a makefile dependency bug in virt-p2v; I'm going to post
the patch for that.

Namely, even after I modified "dependencies.m4", the disk image did not
get correctly regenerated for "run-virt-p2v-in-a-vm". While the image
*was* regenerated, the intermediate (OS-filtered) deps files were not,
and so the change I had made to "dependencies.m4" did not affect the
actual package installation command line.
(2c) I learned about metacity already being present when I launched an
xterm window from the first dialog of p2v, and attempted to run icewm.
IceWM complained that another window manager was already present; that
was when I found metacity in the process list (pstree).
(2d) I started icewm with "icewm --replace" (as recommended by the error
message from (2c)), and lo and behold, two changes had come into effect:
- the spinner started working
- I actually got an actual Task Bar, where I could see all the windows:
virt-p2v, the GTK debug windows (plural), the XTerm window, and (in
the Tray area) even nm-applet! This is not a small improvement: QEMU
doesn't let me easily inject Alt-Tab, so switching between windows in
the VM environment has been a huge chore (made worse by the many GTK
debug windows).
(2e) That is, elaborating on the second bullet from (2d), not only is
metacity (or else, our setup/usage of metacity) bugged enough to break
the spinner, it even (i) does not offer a functional task bar, (b) does
not show nm-applet -- there is no tray area!
I'm of the opinion that we should just get rid of metacity altogether,
and use icewm. I don't know why metacity is not working, but I consider
metacity a seriously substandard WM anyway, so let's just get rid of it?
Thanks
Laszlo
