Hi, My new M8 installation worked just about fine for the first day. I configured KMail and it was working, the next day KMail wouldn't start anymore. It crashed with signal 11 (SIGSEGV) backtrace: multiple lines of: "(no debugging symbols found)..." and at the end: "[New Thread 1024 (LWP 1033)]" Two days later the KDE media player (noatun) crashed the same way. signal 11 (SIGSEGV) backtrace: multiple lines of: "(no debugging symbols found)..." and at the end: "[New Thread 1024 (LWP 1071)]" ...and the these lines: 0x40fba1d9 in wait4 () from /lib/libc.so.6 #0 0x40fba1d9 in wait4 () from /lib/libc.so.6 #1 0x41029f2c in __check_rhosts_file () from /lib/libc.so.6 #2 0x402b4716 in waitpid (pid=1090, stat_loc=0x0, options=0) at wrapsyscall.c:172 #3 0x407855a8 in KCrash::defaultCrashHandler () from /usr/lib/libkdecore.so.3 #4 0x402b20fe in pthread_sighandler (signo=11, ctx= {gs = 0, __gsh = 0, fs = 0, __fsh = 0, es = 43, __esh = 0, ds = 43, __dsh = 0, edi = 135782992, esi = 135710472, ebp = 135710472, esp = 3221220480, ebx = 1087604564, edx = 4294967295, ecx = 135782992, eax = 1862298880, trapno = 14, err = 4, eip = 1085064628, cs = 35, __csh = 0, eflags = 66054, esp_at_signal = 3221220480, ss = 43, __ssh = 0, fpstate = 0xbfffea00, oldmask = 2147483648, cr2 = 1862298898}) at signals.c:97 #5 0x40f2eb68 in killpg () from /lib/libc.so.6 And today Konsole crashed in exactly the same way as KMail. backtrace: multiple lines of: "(no debugging symbols found)..." and at the end: "[New Thread 1024 (LWP 971)]" None of the 3 wants to start anymore. I didn't really care about KMail and noatun but Konsole is something I can't miss. What am I doing wrong ? Thanks in advance, Voutah
