Simon,
I have been experiencing this error for quite some time. If I load a r
script by double clicking it, it happens nearly 100% of the time. If I
load R itself first then it doesn't happen. If I clear the "recent"
files area it doesn't happen until I fill it again. The file opened
seems irrelevant, as does the location of the file (admittedly, all in
user space or external drives).
Despite the dire warning, if I hit escape I can continue working
nearly indefinitely without issue (my script save rate increases to
compensate for risk).
This was reported by CW on Nov 4th (perhaps others before), email
entitled: "[R-SIG-Mac] R segfault at startup, causing R crash". I
worked a little bit with Kevin Ushey offline to get to the bottom of
it further and I thought he pinned it down or at least got closer to
the cause.
"
After playing around with R.app for a bit, I was able to get myself
into a state where R.app was either dying or hanging on startup. I did
the following:
1. Open R.app,
2. Open a new R document (using the icon in the top menu bar --
'Create a new, empty document in the editor' ),
3. Write and execute some code -- in my case, 'x <- 1; print(x)',
executed with Cmd + Enter,
4. (optionally) Repeat steps 2 and 3, creating new documents and
executing more code,
5. Focus a different application,
6. Attempt to open an R document (using the menu bar again --
'Source script or load data in R',
7. Observe that R.app is now hanging.
Note that if you run these repro steps, you may see R segfault / die
on startup (although in some cases all was fine). Note that step 5 is
necessary (IIUC) to force R.app to attempt to save the application
state.
It looks like R.app stores session state in the folder
~/Library/Saved Application State/org.R-project.R.savedState
My hypothesis at this point is that this saved state is somehow
getting corrupted. Removing that folder seems to resolve any startup
crashes I see.
As for the 'Open File' dialog hang, here's what I believe are the
relevant bits of an lldb stack trace I see:

Hopefully this helps...
