XCode debugger locking up

I've been having this problem for some time, but the last couple days
it's become particularly annoying.
Sometimes (usually just when I'm about to find whatever problem I'm
looking for), when stopping at a breakpoint, stepping, moving around in
the stack frame, or doing some other debugger operation that would
cause the display to update, XCode hangs with a spinning rainbow
cursor. During the hang, XCode uses 100% CPU for an inordinate amount
of time (the most recent case was around 8 minutes).
Just before XCode hangs, the status display in the debug window changes
to:
"Timed out fetching variable data. Variable display may be inaccurate."
and eventually (after several minutes) changes to:
"Error from Debugger: Exception Name: NSInvalidArgumentException,
reason:*** -[NSCFArray addObject:]: attempt to insert nil"
If I run Shark during the hang, it shows XCode stuck somewhere down
inside -[NSTextFieldCell drawWithFrame:inView:] for the entire time.
If I wait long enough, whatever operation was going on finishes, and I
can resync with the debugger and continue.
I've tried turning off "Enable Data Formatters" in the
"Debug:Variables" View menu, and also moving aside the .pbxuser and
.mode1 files inside the project bundle, and the problem still recurs.
I've seen very similar problems posted to this list in the past, but I
don't think they were publicly resolved. If anyone out there has any
ideas on how to work around this problem, please let me know.
I can supply Shark or SpinControl output on request.
Thanks,
