nm-applet crashes on "connect to other wireless network"

This is on Gutsy AMD64.

I see exactly the same behaviour on Gutsy x86-64 (0.6.5-0ubuntu10 network-manager-applet package);
here is a backtrace:

and I get a kernel log of:

[17944.979590] nm-applet[6868]: segfault at ffffffffac022dc0 rip 00002b027016df18 rsp 00007fff3cc59540 error 4
(all address varying on each run)

It happens with my kill switch on or off; the wireless is:
05:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG Network Connection (rev 02)

in a Tosh Equium A100 Pro; but it doesn't feel device driver to me.

Dave

I can confirm this bug; nm-applet segfaults with an identical backtrace to Dave Gilbert's. I am using Gutsy AMD64 but with a bcm43xx wireless card.

Same here, using ipw3945 (same as reporter).

Same bug here on gutsy amd64 with iwl4965. seems to be amd64-specific, or can anyone confirm this on i386? I will test it.

im using an intel duo core processor on gutsy 64 bit edition im not using amd so its not specific to amd !

Also happens with me, on amd64. Trying to connect to a network will often just crash the applet. A non-broadcasting, WPA2-secured network, if that matters. Only way I've found to fix it is with a total reboot.

dmesg shows me:

Sorry for the length. Thanks for any help, this is supremely frustrating to have to reboot just because my network fails.

Edit: found I could just run nm-applet. Sorry, very noob of me. :(
