wireshark in a random way falls out

openSUSE12.3 + xfce + wireshark ( i386 )

linux-0em9:/home/ksr # rpm -qa | grep -i wireshark
wireshark-1.8.9-1.16.1.i586
linux-0em9:/home/ksr # uname -a
Linux linux-0em9.site 3.7.10-1.16-desktop #1 SMP PREEMPT Fri May 31 20:21:23 UTC 2013 (97c14ba) i686 i686 i386 GNU/Linux
linux-0em9:/home/ksr # 

by means of tcpdump I created the testpbx1.log file.
I launched wireshark and I opened the testpbx1.log file.
in case of movement according to the file falls out (under abnormal condition comes to the end) wireshark.
Regularity of these abnormal terminations I didn’t find.
With the file it is impossible to work - wireshark falls out

Please, help me.
