Rgui.exe does not crash if I do not access GUI Preferences (i.e., if I just use
R), and it does correctly use Bitstream Vera Sans Mono as my font. Nor does it
crash if I edit RConsole to set the font back to Lucida Console and then try to
access GUI Preferences.
I've found the bug, and a partial fix will appear in R-devel and
R-patched shortly. The problem is that the dialog assumed you're using
one of the fonts in its list, and the Bitstream font isn't there. If
you'd like to edit the code to allow a more general font selection (any
fixed width font on your system would make sense) I'd consider a patch,
but I don't have time to do that. All I've done is allow you to type in
any valid font name, or put it into Rconsole, which is more or less
equivalent.
A problem with my partial fix is that the sample text doesn't get
updated after you change fonts: because of limitations in the ancient
GUI toolkit we use, there are no notifications sent when you select a
font other than by choosing from the predefined list. The whole thing
needs rewriting (and has for years), but that's certainly not something
I'm planning to take on.
