Pidgin avahi/boujour plugin causes hard system freeze

Bug Description

Binary package hint: pidgin

Ubuntu 8.10.1

I have reported a bug in thinking that the system freeze was caused by either vmware or avahi.

But after my latest test, I've discovered that it was actually the avahi/bonjour plugin in Pidgin that causes the system freeze.

I have described what happens in my bug report at the top of this post.

To quickly summarize:

1) Laptop boots up with Vmware net devices and avahi
2) Network Manager connects to my local wireless network
3) As soon as NM connects, avahi kicks in and wants to add my wireless device as an interesting mdns point
4) BANG, total system freeze. Not even the Magic Keys work on the kernel.

I have discovered that by disabling the Bonjour plugin in Pidgin that this problem doesn't occur.

On Ubuntu 9.10 pidgin 1:2.6.2-1ubuntu7 when I enable my Bonjour account in Pidgin, I get an immediate system freeze, requiring me to switch off power. This is a physical machine, no virtual.

I am having the same problem (on a real system) on Karmic. Enabling a Bonjour account causes my system to freeze with the Caps Lock light blinking. I have not found anything in the logs, and running Pidgin with the Debug Window open doesn't provide any useful information, since the screen goes black when the freeze occurs. I haven't tried running from a Live CD.

Ive got the same problem on SuSe 11.4 my system freezes and I cant login or ftp in without a hard re-boot (switch off) and on all occasions AVAHI-DAEMON is the last process running:

Nov 10 15:43:41 jscosysv avahi-daemon[1659]: Received response from host with invalid source port 49559 on interface 'eth1.0'
Nov 10 15:44:58 avahi-daemon[1659]: last message repeated 4 times
Nov 10 16:22:47 jscosysv acpid: 1 client rule loaded
Nov 11 09:31:25 jscosysv kernel: imklog 5.6.5, log source = /proc/kmsg started. (After hard re-boot)

So I have disabled AVAHI hopefully this will cure the problem. John Proctor Lecturer in computing at Tresham College
