What is your window manager ? Could also be related to that.

Upstream at: http://members.dslextreme.com/users/billw/gkrellm/Bugs.html mention also some potential issues wrt the -w usage.

That's fvwm2, I can try with others and without the -w.

Same happens for me on a mageia 3 i586 kde upgraded from mageia 2.

I ran on gdb and got the following backtrace. It seems it is linked to nvidia drivers. Do you use also nvidia drivers Henrik?

I can confirm that it comes from the nvidia drivers, so I have added anssi in the CC list. I have no crash if I used the nouveau driver. I'll try to get more info on the backtrace by installing the debug nvidia packages.
Master anssi, if you have any suggestions, I'll take them.

Cheers,
chris.

With all debuginfo-installed; and nvidia drivers loaded. It seems I am still missing some debug info on the nvidia-current, is that because it is tainted?

The problem appears to be a double free, which really isn't the end of the world and should (I think) raise a SIGABRT.

I patched the function run_sensors_thread in sensors.c like this:

static void
run_sensors_thread(void)
	{
	GError *error = NULL;
	if (thread_busy)
		return;
	thread_busy = TRUE;
	signal(SIGABRT, SIG_IGN);
	g_thread_create(read_sensors_thread, NULL, FALSE, &error);
	if(error != NULL)
	  printf(" %d %s\n",(uint)error->code, error->message);
	signal(SIGABRT, SIG_DFL);
	}

Note that you do have to #include <signal.h> at the top of the file for this to work.

This is consistent with the signal handling that is initialized in main() and, so long as that double free is the only error that pops up in the Nvidia driver, this ought to let things keep running.  I hope.  We'll see, anyway.

sorry about the multiples.  I did not realize that they were actually getting posted, when I was getting a login message after submitting (cookies were blocked).

Sorry...the mod I made can't work.  Move the signal commands to enclose the for loop in read_sensors_thread() and that should work.

I use it without the -w on KDE with Driver "nvidia" without issue.
There is no new upstream version. 
Should we include a patch based on the upper code ? Would someone provide one clean that apply on the latest SVN version ?

I don't have this bug anymore with latest nvidia kernel drivers, if that the case for others, we should simply closed the bug as resolved!

I had reported this as  a bug, I think last summer. It is no longer a problem. Thanks for the fix.

Closing then..
