System Information
MacOS 10.9

Blender Version
Broken: Blender 2.69 pre git migration
Worked: Blender 2.69 pre git migration

Short description of error
Starting up blender on MacOS with --debug argument and
my old (pre-git migration) startup prefs causes a crash.
The main->build_commit_timestamp is
7956574615470342144
which seems suspicious.

Exact steps for others to reproduce the error

I guess you have to put the attached file in the userprefs area,
but maybe any old userprefs tickles this bug on a Mac.

Here is stack trace:

I looked at filepath in BLO_read_from_file and its value is
filepath const unsigned char * "/Users/trickey/Library/Application Support/Blender/2.69/config/userpref.blend" 0x00007fff5fbff0b0

I attach that file.
userpref.blend

I meant to say that it is broken in a post-git migration build,
specifically one with last commit
f8eb006d09

Removing my old userprefs.blend file fixes the problem,
so this isn't an urgent bug to fix, but maybe want to
protect in code against null time structure returned from lib.

I can't reproduce this on linux, guess it's related to OSX implementation.

Fixed r84c30edbdfe00bc3b8f39504c4dff5ab607f3ece

Developer note:
compiled debug glibc to see why getmtime returns NULL, the input value is overflowing.

Reopening.

I'm not happy with this fix.

Howard, its not just wrong timestamp. It's also short SHA1 of the blender revision which is set to "own". This is not normal.

Now, couple of questions:

How did you produce such a file?
What do you see in the splash screen?
Please provide System Info

I thought this was a file that was saved as user prefs before the
git migration. It was mainly setting emulation of three-button mouse
and a couple theme changes, followed by 'Save User Preferences'.
I am pretty sure that it was saved pre-migration because my
runs started from XCode have --debug as argument always, and the
crash happened the first time I ran from XCode on my Mac after compiling
a git-checked-out source tree.

I tried to look at the splash screen before reporting the bug,
but it was blank where I expected to see the revision info
(unless I was being blind, as my wife sometimes accuses me of :)

The system is MacOS 10.9 (Mavericks), on a Macbook Pro several years old.
I think the XCode on the machine is up to date with the latest revision
but could check if that's important.
