Subject: 23.2; Fail to parse GTK font size with decimal point
Date: Wed, 16 Jun 2010 01:15:23 -0700

[Message part 1 (text/plain, inline)]

Running emacs-gtk, I have my default font set to 'Monospace 7.5' in
gconf which causes emacs to fail to start with the following error
message:

$ emacs
Font `Monospace 7.5' is not defined


Emacs is mis-parsing the font name, not allowing for the point size
field to contain a decimal point.

Here's a patch:

Applied.  But on my system it seems I get 7 even if I specify 7.5.  I tried a 
couple of applications, they all behave the same.

But apparently the patch fixed the bug on the original reporter's
system?  There was no followup here, so I'm closing the bug report, but
if it turns out that this is still a problem, please reopen.
