I was playing a MKV File. While hovering over the Window-Close Button, DragonPlayer crashed with a SegFault. The KDE Bug Assistant tells me, this was already reported and fixed with ticket 325311. But since the mentioned ticket about KDE 4.8.5, and i am using KDE 4.13.0 (Kubuntu 14.04), I don't think so. Reproducible: Sometimes Application: Dragon Player (dragon), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". __lll_lock_wait () at ../nptl/sysdeps/unix/sysv/linux/x86_64/lowlevellock.S:135 [Current thread is 1 (Thread 0x7f097a7707c0 (LWP 3746))] Thread 11 (Thread 0x7f095c3da700 (LWP 3756)): #0 pthread_cond_wait@@GLIBC_2.3.2 () at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185 #1 0x00007f0974176c07 in g_cond_wait () from /lib/x86_64-linux-gnu/libglib-2.0.so.0 #2 0x00007f0965e8e6ac in ??
