backend crashed with ValueError in loads()

Lucid w/updates as of 16 Mar 2010 in VBox 3.1.4 r57640 on Ubuntu 8.04.4. Dell Latitude D800 1.4 Ghz notebook.

"System Testing" (checkbox) runs my requested tests, but will not submit to Launchpad. Reports backend crash.

It`s affecting me too. I`m using Ubuntu 10.04 i386 from 2010-03-18. ISO-testing.

Please do not assign bugs to yourself unless you intent to fix it.

sorry i'm mistake,
 this bug affecting me, i'm new user in this wiki sorry for this error

Salvatore.

I just got the same error while running the system test for uploading the info

the rest seems to be quite stable so far

affect me after BUG: #542695

No recollection of this crash. There was a system hang on first run after reboot command on initial installation via USB key which resulted in a failure to shut down, then running normally after first full startup sequence. That might have been it.

was trying to install vbox while firefox open. think i ran out of memory only 512mb in this machine

I was only closing checkbox without running any tests. Then this one came up.

Same thing here on a 64-bit system....

I was also getting notification about kernel crashes, when running checkbox. I didn't find anything interesting in dmesg, except for few deprecation warnings from sysfs:

[ 250.029201] thinkpad_acpi: WARNING: sysfs attribute hotkey_enable is deprecated and will be removed. Hotkey reporting is always enabled
[ 250.029301] thinkpad_acpi: deprecated sysfs attribute: access by process with PID 2161

[ 250.032230] thinkpad_acpi: WARNING: sysfs attribute bluetooth_enable is deprecated and will be removed. Please switch to generic rfkill before year 2010

Put my netbook into standby while I had my tea. Crash report indicted when returning from standby, Had Firefox open, nothing else. No noticeable crash.

Still valid for me: Lucid beta 1 in VBox 3.1.6 r59338 w/Guest Additions on Ubuntu 8.04.4. Hardware: Dell Latitude D800 notebook 1.4 Ghz.

This seems to happen if you close checkbox with the red "X" which really is the only way to exit it other than proceeding through everything.

I tried to run checkbox (amd64, not virtualized) and got messages that no hard drive was found. Closing checkbox using red X button generated this crash. Needless to say I do have a hard-drive; this is not a netbook, running lucid beta fully-updated as of March 26th 2010 10 am PDT.

Same thing happened to me as described by Stephen.

Attached the saved checkbox output as html file.

Same issue for me when closing an error on amd64

This occurs on my Dell inspirion 1525 after a hibernate.

Occured on my Dell Studio 1749 after a hibernate

I didn't actually run any test just opened System Testing, clicked Next, then closed the window. Lucid 10.04.

Just got this bug on March 31st amd64 daily build of lucid.

All updates 1st April amd64, checkbox gives same problem as above, but checkbox didn't skip any tests itself, I skipped quite a few though.

This bug was fixed in the package checkbox - 0.9.1

Using 64 bit system, crash report detected following close of System Testing app, no unusual behavior whilst in use.

checkbox 0.9 still in the beta 1 ISO, so hopefully will be included in the next beta ISO.

The current version is 0.9.1 in Lucid, so it should be available later today/tomorrow when Beta 2 is released.

This bug still appears to be in 'System Testing' in the final release. downloaded new release 30/04, run from Live USB, run System Testing and run through teh mionitor tests - do not supply email address, just view the report, then "finish", and as soon as user clicks finish, "backend" process takes one core to 100% usage. Using top, user can see Backend process running as root, and is able to kill it to restore cpu to normal usage.

This bug still occur.

I upgraded my 9.10 to 10.04LTS in 2010-05-08.

I try 'System Testing' and it crashes in 'Video Tests', skipping to "delivery report" screen.
