Hi there,
I encountered the same error and found (at least for my install) a solution.
During the upgrade process I didn’t copy the wp-settings.php to the server because I mistakenly mixed it up with the wp-config.php (thought it would overwrite my server settings).
Adding the wp-setting.php to the installation did the trick.
Cheers,
Christian
EDIT:
Logging into my blog it seems that this function _c is needed in some other places as well. So my blog is still broken 🙁
Maybe this is a bug that should be filed?

Hi,
I ran into the same problem while upgrading. I did a few changes to the locale.php file to fix the error. It worked for me but should be considered a hack 🙂
Just comment out the lines with the $trans = and $this->number-format[ (lines 93 and following only)
Hard code your settings for decimals, decimal_point and thousands_sep e.g.
$this->number_format['decimals'] = 0;
$this->number_format['decimal_point'] = '.';
$this->number_format['thousands_sep'] = ',';
this enabled me to run upgrade.php properly.
Hope this works for you too.
so long,
Borgond
