Program crash on Mac

I was sure that I sent this to the list, but maybe it got lost in all
the list confusion.  On the Mac, when adding a new server, I click the
button or select the menu item, the add new server dialog appears.  No
matter what I enter, and it doesn't matter if I click Cancel or OK, I
get a segfault with this error:

*** malloc [23866]: Deallocation of a pointer not malloced: 0xbffff0c0;
This could
be a double free(), or free() called with the middle of an allocated
block; Try setting
environment variable MallocHelp to see tools to help debug

Having changed all the wxLogInfo() calls to wxLogDebug() in the relevant
areas of the program (so they would actually print out, since settings
don't seem the be saved on the Mac), this is the last thing printed
before the error:

13:52:59 Debug: Destroying a connect dialog

This piece of output is located in the frmConnect destructor, all by
itself.  So I can only assume that the offending code is either after
the destructor is called, or perhaps is located in the parent object of
frmConnect.  Wherever it is, my head hurts from debugging, and besides,
I have real work to do (meaning work that pays the bills -- no more real
than that :-).  Maybe someone else can take a look at this.  If not, I
will start looking at it again tomorrow.
