Comment 2 for bug 230809

Was bitten by this too - or something very similar at least.

If I start emacs-snapshot -Q, then M-x customize-face, default, set font-family to unknown-inconsolata, it would work as long as I don't complete anything.
But completing anything would trigger it: e.g., C-x C-f, hit TAB after the "~/".
Leads to a different signal though - segmentation fault (11).

Note that xfontsel thinks that inconsolata has "spc" equal to "p" for proportional. That seems strange. The full XLFDs are:
-unknown-inconsolata-medium-r-normal--17-120-100-100-p-0-iso8859-1
-unknown-inconsolata-medium-r-normal--17-120-100-100-p-0-iso8859-15
-unknown-inconsolata-medium-r-normal--17-120-100-100-p-0-iso10646-1
