Debugger weirdness

I'm working on an app, and have just started compiling it for Intel (on a MacBook Pro). I tried running under the debugger, and got the following in the debugger console:

Exception name: NSInvalidArgumentException, reason:*** -[NSCFDictionary setObject:forKey:]: attempt to insert nil key Parser (0x16daf640) parse buffer: '65^done,globals=[varobj={exp="gDefaultFont",value="0x312920",name="var1",numchild="6",type="class NSFont *",typecode="PTR",dynamic_type="class NSFont *",in_scope="true",block_start_addr="no block",block_end_addr="no block"}] (gdb) ' parse buffer lengeth = 232 current char index = 224

This repeated a second time, and then I got:

Timed out fetching data. Variable display may be inaccurate.

I *think* this is a problem with Xcode/GDB, but I'm not certain. gDefaultFont is a global, and the debugger eventually stopped on a breakpoint involving it. Trying po gDefaultFont in the console seems to stall.

When run again, gDefaultFont is no longer checked in the Global Variables dialog, and things seem OK (and I can po gDefaultFont). --
