No lock-up with -nw. I see the message you describe like this:

(gdb) b iain
Function "iain" not defined.
Make breakpoint pending on future shared library load? (y or [n]) n
(gdb)

I seem to mainly see the dialog after reloading my program to flash with 
watches present (none called var6). When finished reloading the watch 
window comes back empty and then when I try to add the watches back it says:

Title: Application Error
Large red "X": Error: invalid command name "var6"
Buttons: OK	Skip Messages	Details>>

Clicking on "Details>>" I see this:
invalid command name "var6"
invalid command name "var6"
     while executing
"$var delete"
     while deleting object "::.watchwin0.watchwin" in 
::WatchWin::destructor (body line 11)
     invoked from within
"itcl::delete object ::.watchwin0.watchwin"
     (command bound to event)

Any attempt to add watches results in this same dialog. Also, I may have 
seen it crash if I continue on for a while but usually I just restart 
since I probably need the watches back. Haven't tried your patch yet.
Also, it might be considered a bug in that the watchpoints are not 
remembered between insight restarts or after a reload of flash, at least 
for me. (At least BPs are remembered which is handy.)
