nm-applet segfault

I can not find any way to reproduce the problem. Sometimes i download something from the internet (i.e. updating packages) sometimes i only write a post on the forum or simply comunicate via pidgin.
Maybe i just realise then...

Anyway, after disconnection nm-applet disapears and there is no connection and apllet does not apear again.
#nm-applet &
solves the problem until it occur again.

The next time it crashes and you need start it from the command line, could you do the following:

1- Download the debug packages:
Add the repository:
deb http://ddebs.ubuntu.com/ natty main

Install network-manager-applet-dbgsym:
sudo apt-get install network-manager-dbgsym

2- Run nm-applet in a debugger:
gdb --args nm-applet

You will need to use the "run" command to have it actually start.

3- When it crashes, issue the following command:
bt full

4- Attach the output to this bug.

Thanks in advance.

i started it (before posting this bug) from console by 'nm-applet &' and left it.
those messages shows and repeats few times.

'gdb --args nm-applet'
can i do so without waiting for bug to appear?
can i add this to autorun with 'kill nm-applet && gdb --args nm-applet' to run in virtual terminal?

it is not very often - once, twice a week. i do not use internet for high loads on this computer.

Best regards!

Hi!

I have just made update of my packages and found this:

Quite weird, since my internet connection (WiFi) is still alive, but network manager is dead.
Hope this helps.

Best Regards,
San

Who wants 'where' command output?

Is this still crashing for you?

[San (san-plusnet)]

I reported all my crashes.
The last one is from 2011-02-03.
But previous from 2011-01-22.
Lets wait two or three days, ok?

[Uwe Helm (1forthedoctor)]

it's crashing for me as well. no compiz, ubuntu classic desktop, 2.6.38-3 kernel

I can't do anything with there backtraces sadly, they are partial because you are still missing debug packages (you'd want to install libgtk2.0-0-dbg and libglib2.0-0-dbg).

However, there's an easier way: when you get crashes, make sure apport is running (https://wiki.ubuntu.com/Apport#How%20to%20enable%20apport) for it to catch the crashes automatically and send them as new bug reports, or run 'ubuntu-bug name_of_crash_file.crash' using the name of the relevant crash file in /var/crash.
