test suite (make check) fails

[ib wupperonline de (Ingo Brueckl)]

I'm using gtk+ 2.16.1 with glib 2.20.1 and I'll get the following error in
the gtk+ test suite (make -k check) three times:

  /list-store/swap-begin:
GLib-CRITICAL **: g_sequence_iter_is_end: assertion `iter != NULL' failed
aborting...
FAIL
GTester: last random seed: R02Sdac9a77786be9c46c752f0765458f31b
Terminated
make[5]: *** [test] Error 143
make[5]: Leaving directory `/root/gtk+-2.16.1/gtk/tests'

Is there any known problem with the test suite?

Any help appreciated.
