what is going on here. Why no one will fix this bug ?

I have researched a little bit and found out, that the problem is the second battery. If i remove it, cpufreqd will not crash anymore.

It appears that a fix for this is present in 2.4.1 ( http://www.linux.it/~malattia/wiki/index.php/Cpufreqd ):

        Fix segfault on reading the second battery value "

close_battery() is called after open_battery() fails, which obviously won't work! (close_battery() attempts to free unallocated memory; glibc detects info[x] is an invalid pointer)

A race condition exists between enumeration and reading of attributes, this is triggered in my case by the ACPI BIOS randomally making the battery disappear and reappear whilst transitioning between AC/Battery, it's much more likely to occur with multiple batteries due to the larger window .
