KDirLister::handleError(KIO::Job*) (kdirlister.cpp:81) makes a call to <tt style="background: #ebebeb; font-size: 13px;">job->error()</tt> right before calling <tt style="background: #ebebeb; font-size: 13px;">handleError</tt>, for instance.</p>
<p>Is it possible that the widget itself has been deleted early somehow? Does the job run on a different event loop (due to threading or similar)?</p>
<p>I think valgrind has some flags you can use to try to generate a backtrace for where a freed block of memory was freed from, which might be useful for debugging.</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R241 KIO</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D10989">https://phabricator.kde.org/D10989</a></div></div><br /><div><strong>To: </strong>jtamate, Frameworks, dfaure<br /><strong>Cc: </strong>mpyne, michaelh<br /></div>
