arpon crashed with SIGSEGV in pthread_kill()

Hi. Today, after turning on computer, ArpON application crashed. On a panel appeared a sign about crash, but ArpON seems to work okay:

,-----[ check arpon ]
| /etc/init.d/arpon status [OK]
`-----

ArpON also logs events to a '/var/log/arp/arpon' file. I did not changed default file ('/etc/default/arpon'), because it already was set for use a DHCP protocol. Anyway, here is a more info about mentioned crash:

* ProblemType: Crash

Also on all Thread Stacktrace available in a crash report, there is 'No symbol table info available.' for all Threads. As we already know, there is available a new version of ArpON - 2.7. While in each Ubuntu version/release still is 2.0-2.1.
