Version: (using KDE 4.2.1) OS: Linux Installed from: Fedora RPMs Akregator crashed once while I was reading posts (with no activity on my part other than reading, apparently triggered by some background updates). This is a one-time observation. Maybe related to bugs https://bugs.kde.org/show_bug.cgi?id=187938 and https://bugs.kde.org/show_bug.cgi?id=188802 ?? Here is the backtrace: Application: Akregator (akregator), signal SIGSEGV 0x0000003a4f8a7f81 in nanosleep () from /lib64/libc.so.6 [Current thread is 1 (Thread 0x7f1e3c627810 (LWP 24581))] Thread 5 (Thread 0x7f1e1ec35950 (LWP 13097)): #0 pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:217 #1 0x0000003e9fa5a817 in QWaitConditionPrivate::wait () at thread/qwaitcondition_unix.cpp:80 #2 QWaitCondition::wait (this=0x7f1e3144ae88, mutex=0x7f1e3144ae80, time=30000) at thread/qwaitcondition_unix.cpp:154 #3 0x0000003e9fa509f9 in QThreadPoolThread::run (this=0x7f1e3101f080) at concurrent/qthreadpool.cpp:135 #4 0x0000003e9fa59852 in QThreadPrivate::start (arg=0x7f1e3101f080) at thread/qthread_unix.cpp:185 #5 0x0000003a504073da in start_thread (arg=<value optimized out>) at pthread_create.c:297 #6 0x0000003a4f8e62bd in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 Thread 4 (Thread 0x7f1e13e3c950 (LWP 13098)): #0 pthread_cond_timedwait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_timedwait.S:217 #1 0x0000003e9fa5a817 in QWaitConditionPrivate::wait () at thread/qwaitcondition_unix.cpp:80 #2 QWaitCondition::wait (this=0x7f1e3144ae88, mutex=0x7f1e3144ae80, time=30000) at thread/qwaitcondition_unix.cpp:154 #3 0x0000003e9fa509f9 in QThreadPoolThread::run (this=0x88fc20) at concurrent/qthreadpool.cpp:135 #4 0x0000003e9fa59852 in QThreadPrivate::start (arg=0x88fc20) at thread/qthread_unix.cpp:185 #5 0x0000003a504073da in start_thread (arg=<value optimized out>) at pthread_create.c:297 #6 0x0000003a4f8e62bd in clone () at ../sysdeps/unix/sysv/linux/x86_64/clone.S:112 Current language: auto;
