Version: (using KDE 4.2.2) OS: Linux Installed from: SuSE RPMs I've powered up my computer, then I've selected several MP3 music files in Dolphin and started SMPlayer. For whatever reason 2 instances of SMPlayer appeared, playing two different tracks simultaneously. I've closed one instance of SMPlayer, and soon after that a Plasma Workspace message box appeared. Its content follows: Application: Plasma Workspace (plasma), signal SIGSEGV 0x00007f8496766ce1 in nanosleep () from /lib64/libc.so.6 [Current thread is 1 (Thread 0x7f849c2e5790 (LWP 3621))] Thread 3 (Thread 0x7f847c9d3950 (LWP 3865)): #0 0x00007f84971a2d59 in pthread_cond_wait@@GLIBC_2.3.2 () from /lib64/libpthread.so.0 #1 0x00007f8497413f79 in QWaitCondition::wait (this=0xa10970, mutex=0xa10968, time=18446744073709551615) at thread/qwaitcondition_unix.cpp:87 #2 0x00007f849ad8510c in QHostInfoAgent::run (this=0xa10950) at kernel/qhostinfo.cpp:260 #3 0x00007f8497412fc2 in QThreadPrivate::start (arg=0xa10950) at thread/qthread_unix.cpp:189 #4 0x00007f849719f070 in start_thread () from /lib64/libpthread.so.0 #5 0x00007f849679810d in clone () from /lib64/libc.so.6 #6 0x0000000000000000 in ??
