Hi guys.
I'm asking for a little help with xsensors. I'm trying to make it work
with the new lm_sensors: there's a patch and it fixes compilation
errors, but I can only get a segfault when I run the program.

Debugging (after adding '#define DEBUG_XSENSORS') finds the
incriminated function, add_sensor_tab() in src/gui.c:

(gdb) run
Starting program: /usr/bin/xsensors

I can't get beyond this: gtk is not in my knowledge base, and the
function just looks ok to me.
Can anybody help me? Attached you can find the PKGBUILD.

Thanks,
Corrado

Hi bardo, I try debugging and I found that errors aren't related to gtk code.
The main problem is when current->next (line 476 of gui.c) point to 0x00
(is null). Then , the sigsegv is caused on line 502, by
switch ( current->feattype ), because current is null. I insert some control,
now I can't receive sigsegv anymore, but I think that the program doesn't run
properly.
The controls that I've insert are like if ( current != NULL ) { ... }.
If you want to see proof-of-concept patch, conctact me in pvt, I think
that we're annoying the readers

Thanks for the great work, I'm going to test the patch you sent me as
soon as I can. I'll continue the discussion in private, if needed.
