sysinfo crash

[phill3006]

Whenever I click on system in sysinfo, the program appears to crash. The window closes (do you still call them windows when you're running linux?) and it ceases to appear in the lower panel. What's happening?
I'm running a Dell Dimension 3000. The 2004 model if my math is correct.

With me the same. Feedback I get from sysinfo is this:

What's yours? (You can see it if you first open Terminal (Ctrl+Alt+t) and then just type sysinfo)


(Might be just a bug to inform to the makers of sysinfo...)

Same here, but it only crashes when I click "System", if I just want to look at other components it doesn't crash. If you really want it you may consider downgrading it to the Lucid version.

Here's my error nonsense.
"Exception in Gtk# callback delegate

[grey1beard]

I'd noticed the same effect of Sysinfo window closing when you clicked on System in my meerkat running with the amd6d version.
If I typed sysinfo in terminal, I only got

GConf.NoSuchKeyException: Key '/apps/sysinfo/window_width' not found in GConf
at GConf.Client.Get (System.String key) [0x00000] in <filename unknown>:0

None of the "Exception in Gtk# callback delegate...."etc.

Same here.

Run sysinfo. fine looking at all the other parameters but as soon as I click on System the app bombs out / disappears. Output from terminal..

If anybody has any ideas that would be great

[josephellengar]

me too. only system tab.

[albertnet]

It happened to me as well, once selecting system it would close, so I decided to change settings so the system tab would be the one that shows when it opens and guess what?... Now I'm unable to get it working:confused:
It only opens and closes it immediately, what a disgrace. It happens in both 64 and 32 meerkat flavours. Does anyone knows if there's a command line config to reset it to it's default and see it again? Thank you guys.

By the way, please don't do as I did, it's kinda silly haha.

It doesn't look like there is anything that we can do to me. I ran it and got the same output. And since the top part of the call stack is a null reference, that means that the program has some bad exception handling or dangling pointers. That won't work regardless of system configuration. Probably a problem with a specific version of the program. Is everybody else here also on 64 bit?

Ok guys, so I kept reading and thought to try it as sudo, I did it and the program runs not using the preferences before set as a regular user (I'm the one that changed in preferences the main window to be "system" and then the program wouldn't open), however it still crashes when selecting the System tab. I'm running meerkat 64 & 32, in both the result is the same.
This is the terminal output when running as sudo:

albertnet@Ultron:~$ sudo sysinfo

And this is the output as regular user:

Is this of any help?

I have the same problem in Meerkat, crashing when clicking System.
But the question is: what's supposed to say in System?
The other sections seem to encompass everything a system has. Also I just noticed that in the Welcome screen under Hardware there is a pull-down menu on upper right corner that says "Motherboard", "Graphic Card", "Sound Card", and "Network", that's pretty much all the system to me.

[britbrian]

I had same problem with it crashing on System item
so I followed the thread given above
https://bugs.launchpad.net/ubuntu/+source/sysinfo/+bug/596727

sysinfo_0.7-4_all.deb fixes it and is set for Natty.
You can download it for Meerkat too and it works as expected.
