fluxbox unshade crashing GTK2 applications?

[L Campbell]

(This probably isn't the right place to ask, but I figured I'd start
here and head upstream if necessary).

Since updating to fluxbox 1.1.0.1 last night (and x11-toolkits/gtk20
to revision 1), attempting to unshade a shaded GUI application is
causing the application to segfault with a BadAlloc X Window System
error. This behavior was not observed before updating. Tested with
www/firefox3, graphics/gimp and graphics/inkscape. For all three
applications, unshading produces the following error --

The program 'gimp' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 3250 error_code 11 request_code 53 minor_code 0)
  (Note to programmers: normally, X errors are reported asynchronously;
   that is, you will receive the error a while after causing it.
   To debug your program, run it with the --sync command line
   option to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

I'm not really sure if this is an issue with fluxbox, GTK, or my own
configuration. It seems like only GTK2 applications crashing --
audio/aumix uses GTK 1.2 and doesn't crash on unshade. Relevant
version information follows, please advise on appropriate course of
action :(
