[lazarus] TImage not displaying image?

Okay, I grabbed the CVS just now and rebuilt.  The editor is there and
it displays fine during editing.  Now, I launch my program with the
TImage on the form and have a button to load from file and as soon as it
does, it crashes.

Here's the code:


The bitmap was originally true color.  After that crashed I reduced it
to 128 colors indexed and RGB both to no avail.  Here's what happens in
the console window when the app is run and this line is called:

Form Stream "TFORM1" Signature=TPF0
TPicture.LoadFromFile A TBITMAP
TPicture.LoadFromFile B TBITMAP
TPicture.LoadFromFile C 
TPicture.LoadFromFile D 
TPicture.LoadFromFile E 
TPicture.LoadFromFile F

I know everything's not finished yet with lazarus (and probably never
will be :-) so I apologize if I'm asking a stoopid question about a
feature that just doesn't work yet, but Andrew stated I should be able
to load the image at runtime...  Transparency and Autosize are both
turned off.
