Just to clarify here - TBitBtn is not causing the crash.  It is an issue in 
older pixbuf's made apparent on account of my incomplete code. Arrgh I wish 
I had a test system, w/older libs. but I don't.  IF I am correct this issue 
is caused by the little blip of garbage data(which is by the way a properly 
formatted BMP) in the lfm file on TBitBtn. So. If you

1.)turn of  TBitmap.ReadStream by inserting an exit; right after begin,

and (if you aren't already)

2.)use LoadFromXPMFile in TBitmap.LoadFromFile  instead of inherited

and then

3.) recompile Lazarus

Programs you make should work, because it never actually reads the BitBtn 
Glyph from resources.

I hope this works for you, as it is a simple if temporary fix.  Sorry for 
all the bother.. but I did warn that the streaming portion was incomplete & 
very Dangerous. I just never thought about how it would affect TBitBtn's.

Andrew
