Package: i2c-tools
Version: 3.1.0-1
Severity: grave
Justification: renders package unusable

Dear Maintainer,
when I run $ decode-dimms I get this error:

12:21:03 enrico@beatrice-sid:~$ decode-dimms
# decode-dimms version 5929 (2011-02-16 14:58:38 +0100)

Jean Delvare, Trent Piepho and others
Can't use string ("") as a HASH ref while "strict refs" in use at /usr/bin/decode-dimms line 1783.



Thanks
Enrico

This package contains many more than only decode-dimms. Are the others
binaries also broken? If not I don't think the package can be called
unusable.

Dear Maintainer,
when I run $ decode-dimms I get this error:

This is not something reproducible at least on the few machines I have
tried. It is likely related to the data you have in /sys on your system.
Can you please run the following command and send the resulting file:

tar -cvzf eeprom.tar.gz /sys/bus/i2c/drivers/eeprom/

I don't know the name of other binaries provided by i2c-tools, can you
give me some examples?

What can I do?

Can you please send me the list of files present in
/sys/bus/i2c/drivers/eeprom/ on your system ? You should have files in
the form x-xxxx.

Do you also have a /sys/bus/i2c/drivers/at24 directory? If yes, can you
please send me a tarball of these files?

I don't have this directory:
