Can you install the "kdelibs5-dbg", "kdebase-workspace-dbg" and "libqt4-dbg" packages and try to reproduce the crash to get a complete backtrace? Thanks #14 0xb65aae51 in KIO::NetAccess::synchronousRun () from /usr/lib/libkio.so.5 #15 0xa92cdc0f in ?? () from /usr/lib/kde4/plasma_applet_cwp.so so the "customizable weather plasmoid" is the only thread that's actually running in this crash, and it's calling KIO methods from a separate thread. if you remove the CWP widget, does this crash go away? i dont have the plasmoid and there's no crash. # kde 4.3 not even w/ the plasmoid added I removed the customizable weather plasmoid, but I still get the mouse freeze. This time I did not get a KDE crash handler message, so I couldn't give you a backtrace. I had to do a "kquitapp plasma" to unfreeze. Will install the dbg packages and post the output. With the kde debug packages installed, the crash handler says: Application: Plasma Workspace (plasma), signal SIGSEGV [Current thread is 0 (LWP 4369)] Thread 3 (Thread 0xa6afeb90 (LWP 4397)): #0 0xb7f4a424 in __kernel_vsyscall () #1 0xb4ff9f65 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/i686/cmov/libpthread.so.0 #2 0xb7e5585d in pthread_cond_wait () from /lib/i686/cmov/libc.so.6 #3 0xb67c0502 in QWaitCondition::wait (this=0x8fbd140, mutex=0x8fbd13c, time=4294967295) at thread/qwaitcondition_unix.cpp:87 #4 0xa92e8a5a in RenderThread::run (this=0x8fbd134) at ../../../../plasma/wallpapers/image/renderthread.cpp:91 #5 0xb67bf522 in QThreadPrivate::start (arg=0x8fbd134) at thread/qthread_unix.cpp:188 #6 0xb4ff64b5 in start_thread () from /lib/i686/cmov/libpthread.so.0 #7 0xb7e46a5e in clone () from /lib/i686/cmov/libc.so.6 Thread 2 (Thread 0xa62fdb90 (LWP 4821)): #0 0xb7f4a424 in __kernel_vsyscall () #1 0xb7e3efe1 in select () from /lib/i686/cmov/libc.so.6 #2 0xb688ec20 in QProcessManager::run (this=0x8c052d8) at io/qprocess_unix.cpp:296 #3 0xb67bf522 in QThreadPrivate::start (arg=0x8c052d8) at thread/qthread_unix.cpp:188 #4 0xb4ff64b5 in start_thread () from /lib/i686/cmov/libpthread.so.0 #5 0xb7e46a5e in clone () from /lib/i686/cmov/libc.so.6 Thread 1 (Thread 0xb4c1b720 (LWP 4369)): [KCrash Handler] #6 0xb69e6016 in QDBusAdaptorConnector::relaySlot (this=0xa7304f90, argv=0xbf96797c) at qdbusabstractadaptor.cpp:268 #7 0xb69e69a8 in QDBusAdaptorConnector::qt_metacall (this=0xa7304f90, _c=QMetaObject::InvokeMetaMethod, _id=0, _a=0xbf96797c) at qdbusabstractadaptor.cpp:364 #8 0xb68c5ad3 in QMetaObject::activate (sender=0xa7300a28, from_signal_index=0, to_signal_index=1, argv=0xbf96797c) at kernel/qobject.cpp:3112 #9 0xb68c5f00 in QMetaObject::activate (sender=0xa7300a28, m=0xb699d628, from_local_signal_index=0, to_local_signal_index=1, argv=0xbf96797c) at kernel/qobject.cpp:3206 #10 0xb68c5f8b in QObject::destroyed (this=0xa7300a28, _t1=0xa7300a28) at .moc/release-shared/moc_qobject.cpp:143 #11 0xb68c6d99 in ~QObject (this=0xa7300a28) at kernel/qobject.cpp:757 #12 0xb6569b7d in ~Scheduler (this=0xa7300a28) at ../../kio/kio/scheduler.cpp:246 #13 0xb656d2f4 in destroy () at ../../kio/kio/scheduler.cpp:102 #14 0xb64ab80b in ~KCleanUpGlobalStatic (this=0xb6676054) at ../../kdecore/kernel/kglobal.h:62 #15 0xb7d95589 in exit () from /lib/i686/cmov/libc.so.6 #16 0xb7d7b7ad in __libc_start_main () from /lib/i686/cmov/libc.so.6 #17 0x080484d1 in _start () at ../sysdeps/i386/elf/start.S:119 Mh, the last crash seems more like bug 189592. Thanks The crash was caused by the CWP widget (using KIO on a secondary thread) Update it to the latest version or remove it. Regards *** This bug has been marked as a duplicate of bug 189592 *** |
Version: (using KDE 4.2.4) Compiler: gcc version 4.3.3 (Debian 4.3.3-14) OS: Linux Installed from: Debian testing/unstable Packages I have my wallpaper type set to "Image". If I select a wallpaper from the dropdown list, it works. If I click the little floppy disk icon to the right ("Browse" according to the tooltip) to select an image of my own choice, nothing happens (no file selection dialog) except that my mouse stops working. After a while, the keyboard stops responding as well. Several minutes later, the KDE crash handler tells me that plasma has crashed, and displays the following details: ------------------------------------- Application: Plasma Workspace (plasma), signal SIGSEGV [Current thread is 0 (LWP 4284)] Thread 9 (Thread 0xa9298b90 (LWP 4288)): #0 0xb7fd8424 in __kernel_vsyscall () #1 0xb5040f45 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib/i686/cmov/libpthread.so.0 #2 0xb7ee478d in pthread_cond_wait () from /lib/i686/cmov/libc.so.6 #3 0xb6812822 in QWaitCondition::wait () from /usr/lib/libQtCore.so.4 #4 0xb52ebfd2 in ??
