Could you perhaps elaborate on how to reproduce this? <offtopic>Simple comment/thought: shouldn't the QProcess be disconnected on "KJavaAppletServer::quit"/"~KJavaAppletServer", so it won't retrigger a data read, and then causing the crash ?</offtopic> (In reply to comment #2) > <offtopic>Simple comment/thought: shouldn't the QProcess be disconnected on > "KJavaAppletServer::quit"/"~KJavaAppletServer", so it won't retrigger a data > read, and then causing the crash ?</offtopic> Actually this is a very valid point. Another bug report, bug# 281099, seems to have a similar reason for crashing. Git commit 6bc46d11b1204d437fea92c5ea2115f238360050 by Dawit Alemayehu. Committed on 19/11/2011 at 21:58. Pushed by adawit into branch 'KDE/4.7'. When KJavaAppletServer's dtor is called, disconnect from KJavaProcess first to avoid crashes.
