Gimp @2.6.11 crashes when selecting "curves" tool

[juergen@…]

I can reproducibly crash the GIMP by doing the following:

• Start GIMP (it does not matter whether it's started from a bash or from the MacOS GUI)
• Open some image
• Select the "curves" tool
• wait about a second

On stderr, I see the following:

[me@mymachine ~]$ gimp &
[1] 14985
[me@mymachine ~]$ 
(gimp:14985): GLib-WARNING **: goption.c:2132: ignoring no-arg, optional-arg or filename flags (8) on option of type 0

(script-fu:15166): LibGimpBase-WARNING **: script-fu: gimp_wire_read(): error

[1]+  Exit 1                  gimp

Since this error does not occur with any other Xorg-based program, and does not occur on a Linux box using the same software versions, I assume that something's wrong with the port. I'll gladly provide more information if you tell me what to look for.
