Thanks for the bug report, I'm going to close it since I'll remove the code that check for jobs and put them on a tray icon, I could fix this but as I'm going to write a plasmoid the kded will stay there for another task that doesn't block it. |
Version: SVN (using Devel) OS: Linux When no local CUPS daemon is running, print-manager fruequently causes kded to hang until the connection timeout occurs. I’m not sure whether CUPS needs to be configured for this to happen. Reproducible: Always Steps to Reproduce: 1. stop any running CUPS daemon 2. start kded4 with print-manager installed Actual Results: kded4 hangs while attempting to connect to a non-existent CUPS daemon, causing any applications communicating with kded4 to hang as well, making almost all of KDE unusable Expected Results: kded4 does not hang Backtrace: #0 0x00007ff2fcfb31bd in connect () from /lib64/libc.so.6 #1 0x00007ff2dd59718d in httpAddrConnect () from /usr/lib64/libcups.so.2 #2 0x00007ff2dd59684c in httpReconnect () from /usr/lib64/libcups.so.2 #3 0x00007ff2dd5968e6 in httpConnectEncrypt () from /usr/lib64/libcups.so.2 #4 0x00007ff2dd5b1d8f in _cupsConnect () from /usr/lib64/libcups.so.2 #5 0x00007ff2dd5b2e75 in cupsGetJobs2 () from /usr/lib64/libcups.so.2 #6 0x00007ff2dd7caa79 in PrintD::checkJobs (this=0x8db580) at /stuff/kde/ramfs/kdeplayground-base-1194799/print-manager/printd/printd.cpp:80 #7 0x00007ff2dd7c95d4 in PrintD::qt_metacall (this=0x8db580, _c=QMetaObject::InvokeMetaMethod, _id=<value optimized out>, _a=<value optimized out>) at /stuff/kde/ramfs/kdeplayground-base-1194799/build/print-manager/printd/moc_printd.cpp:76 #8 0x00007ff2fbaebda1 in QMetaObject::activate(QObject*, QMetaObject const*, int, void**) () from /usr/lib64/libQtCore.so.4 #9 0x00007ff2fbaea209 in QObject::event(QEvent*) () from /usr/lib64/libQtCore.so.4 #10 0x00007ff2fae95534 in QApplicationPrivate::notify_helper(QObject*, QEvent*) () from /usr/lib64/libQtGui.so.4 #11 0x00007ff2fae9db7f in QApplication::notify(QObject*, QEvent*) () from /usr/lib64/libQtGui.so.4 #12 0x00007ff2fc7827e6 in KApplication::notify(QObject*, QEvent*) () from /usr/lib64/libkdeui.so.5 #13 0x00007ff2fbad582c in QCoreApplication::notifyInternal(QObject*, QEvent*) () from /usr/lib64/libQtCore.so.4 #14 0x00007ff2fbb05378 in ??
