Crash in dialog_file_access.c (was Re: Trouble compiling)

[David Reiser]

So even though I have 3 dbd files in the location specified in  
configure with --with-dbi-dbd-dir=, my list is still null because  
gnucash hasn't asked for the registered backends yet? If so, why would  
Sebastian's example show a non-null list with a breakpoint at the same  
location?
