Reported using DrKonqi
Created attachment 109225 [details] New crash information added by DrKonqi konsole (16.04.3) using Qt 5.6.1 - What I was doing when the application crashed: Opened Konsole, ran "ls" in a folder, and exited via "exit". - Unusual behavior I noticed: Lots of KDE-related applications tends to crash, especially Konsole after running for a while. I also have some update issues with the taskbar, where the clock sometimes doesn't change the hour (until I mouse over). Plus when I start/exit applications, the other icons start to tear vertically with one half "jumping" up and down over the icon below. -- Backtrace (Reduced): #6 0x00007f9bc5a5c428 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:54 #7 0x00007f9bc5a5e02a in __GI_abort () at abort.c:89 [...] #9 0x00007f9bc5aa57c3 in malloc_printerr (ar_ptr=0x7f9ba4000020, ptr=0x7f9ba40008b0, str=0x7f9bc5bb4c52 "corrupted double-linked list", action=<optimized out>) at malloc.c:5006 #10 malloc_consolidate (av=av@entry=0x7f9ba4000020) at malloc.c:4175 #11 0x00007f9bc5aa8cde in _int_malloc (av=av@entry=0x7f9ba4000020, bytes=bytes@entry=2032) at malloc.c:3450
