<p>Crash report every time is on deleted process, scenarios to me:</p>
<ol class="remarkup-list">
<li class="remarkup-list-item">Kernel bug</li>
<li class="remarkup-list-item">Some newly (plugin / lib and so on) tries to notify or something plasmashell</li>
</ol>
<p>Testing done (no other updates between tests):</p>
<ol class="remarkup-list">
<li class="remarkup-list-item">Suspend / resume -> pacman -Su plasma-workspace -> kquitapp5 plasmashell -> not crash (5/5)</li>
<li class="remarkup-list-item">But continuous suspend / resumes (again i don't perform any updates to be sure when applying same plasma-workspace version) -> pacman -Su plasma-workspace -> kquitapp5 plasmashell -> crash with above delete'd backtrace.</li>
</ol>
<p>Any ideas ?</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R119 Plasma Desktop</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D4667" rel="noreferrer">https://phabricator.kde.org/D4667</a></div></div><br /><div><strong>To: </strong>anthonyfieroni, Plasma, davidedmundson, sitter, dfaure<br /><strong>Cc: </strong>hein, plasma-devel, spstarr, progwolff, Zren, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, lukas<br /></div>
