[Zope] Uncaught exception in OFS.Image with LocalFS

[Brad Crittenden]

hello:

i'm using Zope 2.1.6 and LocalFS 0.1.7.  when i try to view an image via a
LocalFS object i get an exception in OFS.Image.py at line 187:

last_mod =int(self._p_mtime)

the error occurs the *first* time i try to access a specific image with a
recently launched browser.  accessing other images or subsequent hits to the
troublesome image in the same browser do not cause the problem.  subsequent
hits in the same launch of zope from a fresh browser on another machine
causes the exception.

having modified Image.py to catch the exception and dump some information i
see that self._p_mtime is None.  i've looked around but cannot determine
where _p_mtime is defined or how it is supposed to be set.

i see this method in Image was re-written after Zope 2.1.4.

similarly, accessing a .wav file via LocalFS causes the following message:

2000-03-23T16:27:13 ERROR(200) ZServer uncaptured python exception, closing

the wav file is delivered to the browser correctly.

as a quick fix to the Image problem, i catch the exception, set last_mod =
0, and continue.  this does not seem to have any ill effects.
