bug#13385: 24.1; TAB in C file causes type error

[Julian Stecklina]

Hello,

While editing C files, I sometimes stumble upon the following error. I
cannot reliably reproduce its first occurence, but when it occurs it
will break indenting code until I kill the buffer and revisit the file.

I removed all cc-mode customization from my .emacs.el, but it doesn't
make a difference.
