sysinfo crashes when I click on "system": System.NullReferenceException

[ginnyh532]

Binary package hint: sysinfo

I am running Maverick (Ubuntu 10.10). The version of sysinfo is 0.7-3ubuntu1. When I clicked on "system" in the menu, sysinfo crashed with no error message. I expected to see system information.

Please try running it from a shell/console.

For me it crashes with the following backtrace, obviously when trying to get "window_width":

I have the same issue, but only when choosing 'System' from the menu. The other menus don't crash the app.

There is another bug on this machine that reports the wrong version number in "about ubuntu", could this be causing a problem?

Is it going to be "another bug in free software that everyone is experiencing but the developers don't mind or aren't able to fix it in the short term because they will consider it as a minor bug unless they want a complete description with a LOT of details"?

[Iain Lane (laney)]

Looks like the NRE happens at line 320 of Sysinfo/SystemInfo.cs, the function should check for temp == null and break out of the loop if so. I'll patch this in Debian and sync soon if this theory is correct. Thanks for the report.

[Sebastien Bacher (seb128)]

the issue is that the code does "if ( temp.StartsWith("Build Date")) {" but the ubuntu log lines start with [timestamps] markers so there is no match, it would be better to fix the code so the version can be read even if it's not on line start

[Sebastien Bacher (seb128)]

the log start with those though

"X.Org X Server 1.9.0.902 (1.9.1 RC 2)"

so maybe the string should be updated in "if ( temp.StartsWith("X Window System Version")) {" as well

[Hans Joachim Desserud (hjd)]

In one of the duplicates (see bug 613988 for details), the reporter has seen an additional error message which I'm not sure if this is directly linked to this issue or not:
Error org.freedesktop.org.DBus.Error.Spawn.ChildExited: Launchelper exited with unknown returncode 1

From the same report it seems this also affects Linux Mint (makes sense, as it is based on Ubuntu). I tried adding a bug watch for this, but I couldn't find Mint in the list of "Also affects distribution".

[Iain Lane (laney)]

No, I don't know what that is (or if it's a problem). Please file a separate report if so. Anyway, I uploaded the fix some days ago but forgot to close this bug. Done now.

[grikdog (dcoshel)]

What is the release schedule for this "fix" -- i.e., when can we be expected to see a difference in behavior?

Linux Skoojewa 2.6.35-24-generic #42-Ubuntu SMP Thu Dec 2 01:41:57 UTC 2010 i686 GNU/Linux

It is in Natty.

[John Winterton (jwinterton)]

That's nice, how about a fix for the current release? Natty is rather a long time off as the software flows.

Fortunately, one can make some use of lshw in the meantime.

[tecknomage (tecknode)]

Add me to waiting "fix"

Ubuntu 10.10, Sysinfo 7.0

NOTE: Went to URL in Help = http://sourceforge.net/projects/gsysinfo/

Latest Sysinfo listed = v0.6.1-3

Tried install of DEB but....

"Error: Dependency is not satisfiable: libgtkmm-2.4-1"

BUT have libgtkmm-2.4-1c2a installed!

[tecknomage (tecknode)]

Update:

According to "About Ubuntu" I am running v11.04 but I do not remember running a distribution update from v10.10

This is problematic because Sysinfo 7.0 still crashes when "System" is selected on sidebar.

[Sebastien Bacher (seb128)]

the wrong ubuntu version seems to be a bug due to a stable update candidate, not sure if the fix will be backported to 10.10 since this software is not in the default installation and has other equivalents which can be used

[tecknomage (tecknode)]

Ran terminal to check version: cat /etc/lsb-release

I am running Ubuntu 10.10

ALSO FOUND:

Same problem (Open Sysinfo, click System, closes) for me in 10.10

[Jim Bauwens (jimbauwens)]

The bug is fixed, but you will only get the update in 11.04.
At least this is what I understand.

First of all, congratulation to the developers, taking there time to fix it.
You must understand that most developers do this in there free time, so its
not alway convenient to do fix stuff quick.

I believe it is far too early to go to 11.04 as it is still in alpha test. You may not be able to cope with it at that level.

[M. Nease (mlnease-hctc)]

Yes indeed, thanks very much Devs.

[tecknomage (tecknode)]

NOTE:

I just changed to Linux Mint 10 for my laptop.

If you install SysInfo (gets it from Ubuntu Repository) you have the same problem with v0.7-3, I uninstalled it.

Turns out the Mint "HardInfo" data + benchtest utility gets all the info anyway. It's also much faster than Ubuntu's test utility.

[Linuxexperte (andrea-koeth)]

hi technomage,
I can confirm that. The problem in sysinfo is quite nverving. That's why I switched over to Mint "Hardinfo" data + bechtest utility. This app runs stable and is a very good replacement of sysinfo.
The only thing is: Ubuntu does not have this. So it would be a real help for Ubuntu-Users, if this app would be ported over to Ubuntu (because LinuxMint is ubuntu-based).

Greetings
Linuxexperte

at least it's not a trojan :) i've always thought that apps in USC are tested by canonical/ubuntu

I got a similar problem with Sysinfo on mij Ubuntu 10.10.
Cannot open it at all.

[coloradoz (ajsenol)]

An update is available from the sysinfo package section. It is earmarked
for natty, but is available now.

http://packages.ubuntu.com/natty/all/sysinfo/download

Go grap it and install - mine works fine now.

Moonwalker, did you update from http://packages.ubuntu.com/natty/all/sysinfo/download per coloradoz' post? Works perfectly for me in Maverick.

[moonwalker04 (moonwalker04)]

Nease, sysinfo has been working after re-installed and updated, no problems

[Linuxexperte (andrea-koeth)]

hi people,

I installed this new package from the page here and installation ran clean. The program works now clean again.

But what I discovered was, that the installation-window of gedebi refused to close after installation. I had to reboot my machine, to get this window closed in LinuxMint 10 (based on maverick).

Therefore I wanted to konw: is this normal in LinuxMint 10 ? Did anybody else discover the same thing in LinuxMint 10 or even in ubuntu Maverick?

Greetings
Linuxexperte

[Ilis (ilis)]

I installed version 0.7-3ubuntu2 right now and it still crashed

[Linuxexperte (andrea-koeth)]

Hi Ilis,

did you installthe new version 0.7.4?? It works also in Maverick for me. Only this one little thing I discovered is still unclear to me.

Install this new version from the link postet by M. Nease. This package works and does not crash anymore.

Greetings
Linuxexperte

[Ilis (ilis)]

Linuxexperte, thanks!

I'll wait new version in repo. Now I using lshw.

[Phil Norisez (norisezp)]

Running 10.10. I know I'm late to the party, but I just loaded hardinfo via sudo apt-get install hardinfo as suggested by the shell when I tried to run it. This works, and seems superior to sysinfo, anyway.

[Linuxexperte (andrea-koeth)]

Hi Phil Norisez,

I also use this now and this works fine for me and in the Menu there is
also this app Hardware and Benchmarks, which gives the same Information
too. So sysinfo is no longer needed.

Greetings

Hello, I am back :) Now i use the xubuntu 11.10 oneiric kernel 3.0.0-14
-generic. It feels more stable than maverick. So far everything is new and
reliable and there are no bugs yet (i hope), including bugs in sysinfo as
maverick yesterday. Ubuntu is really unparalleled and incomparable, believe
it or not, Lol. Bravo !

Hi, I get the same result while trying to use it in Ubuntu 16.04-5.

I can provide the output of my "lshw" for any use in regard of this bug. (Attached to this comment).

Best regards,
