<p>When you change the icon in <tt style="background: #ebebeb; font-size: 13px;">user-manager</tt> repeatedly, are you prompted for a root password <strong>every time</strong>? On my system (Tumbleweed), there's a "grace period" where I don't get re-prompted and the icon doesn't change reliably.</p></div>

<p>Right, there is a "grace period" of five minutes after every time you enter your password. This is built into PolicyKit, I believe. As far as I can tell from keeping a Dolphin window open showing the contents of <tt style="background: #ebebeb; font-size: 13px;">/var/lib/AccountsService/icons/</tt>, the icon immediately gets updated correctly on disk every single time I change it in <tt style="background: #ebebeb; font-size: 13px;">user-manager</tt>. I'm unable to fully confirm your assertion that the icon only reliably gets changed in Kickoff after being promped for a password. For me, it's a bit more subtle than that: the icon only reliably gets changed in Kickoff the <strong>first</strong> time I change it in <tt style="background: #ebebeb; font-size: 13px;">user-manager</tt> that triggers a PolKit prompt after plasmashell has been started or restarted. I get a blank circle for all other circumstances:</p>
<ul class="remarkup-list">
<li class="remarkup-list-item">Change icon in <tt style="background: #ebebeb; font-size: 13px;">user-manager</tt> after restarting plasmashell less than 5 minutes after the last change, such that there is no PolKit prompt</li>
<li class="remarkup-list-item">Change icon in <tt style="background: #ebebeb; font-size: 13px;">user-manager</tt> twice after restarting plasmashell, waiting more than 5 minutes each time so a PolKit prompt will be triggered; second update does not change Kickoff</li>
</ul>

padding: 0 4px;">@hein</a>'s report that this patch is 100% reliable when <strong>not</strong> using <tt style="background: #ebebeb; font-size: 13px;">user-manager</tt>. I patched <tt style="background: #ebebeb; font-size: 13px;">KUser::faceIconPath()</tt> in <tt style="background: #ebebeb; font-size: 13px;">KCoreAddons</tt> to only ever return the <tt style="background: #ebebeb; font-size: 13px;">~/.face.icon</tt> path, instead of <tt style="background: #ebebeb; font-size: 13px;">/var/lib/AccountsService/icons/$username</tt>, and it becomes 100% reliable. I don't get the "Unsupported image format" error anymore, which is a little odd because the two images are identical:</p>
<p>$ (master) md5sum /var/lib/AccountsService/icons/dev ~/.face.icon <br />
