[fpc-pascal] crash in tobject.free

Hi all,

I'm encountering a consistent crash, and I'm not sure how to address the 

- laz beta, svn 22277, from debian testing -- a rather outdated one, 
because at this point upgrading lazarus requires updating debian
- fpc 2.4.0-2 [2010/02/20] for i386
- fpgui commit e01c52a650bfdcce0bb1c8bbceefeb4e8dd46764

The lazarus popup error message says:

Project Swindow raised exception class 'External: SIGSEGV'.

The top of the lazarus call stack shows:

#0 :00000000 ?? at :0
#1 :08058BC2 SYSTEM_TOBJECT_$__FREE at :0

#2 is my own call: if assigned (f_image) then f_image.free;

I broke up the line, and it's crashing on the "then f_image.free" part, rather 
than on the "if assigned(f_image)" part.

Any ideas?
