sensors-detect segmentation fault.

Hi,
I've installed lm_sensors and i2c on my Via Epia ME6000 with Red Hat 9.
When i run sensors-detect it ends with a segmentation fault after which 
only a reboot helps to kill the processes
Below i've posted what appears on the console, dmseg and lsmod.
Hope you can help. Thanks.


-------------  on console  ------
 BIOS vendor (ACPI): VT9174
 System vendor (DMI): VIA Technologies, Inc.
 BIOS version (DMI): 6.00 PG
 We can start with probing for (PCI) I2C or SMBus adapters.
 You do not need any special privileges for this.
 Do you want to probe now? (YES/no):
Probing for PCI bus adapters...
Use driver `i2c-viapro' for device 00:11.0: VIA Technologies VT8233A/8235 
South Bridge
Probe succesfully concluded.

 We will now try to load each adapter module in turn.
Load `i2c-viapro' (say NO if built into your kernel)? (YES/no):
Module loaded succesfully.
 Do you now want to be prompted for non-detectable adapters? (yes/NO):
 To continue, we need module `i2c-dev' to be loaded.
 If it is built-in into your kernel, you can safely skip this.
 i2c-dev is not loaded. Do you want to load it now? (YES/no):
 Module loaded succesfully.

 We are now going to do the adapter probings. Some adapters may hang 
halfway
 through; we can't really help that. Also, some chips will be double 
detected;
 we choose the one with the highest confidence value in that case.
 If you found that the adapter hung after probing a certain address, you 
can
 specify that address to remain unprobed. That often
 includes address 0x69 (clock chip).
