GLib-CRITICAL errors during build of docs (dev octave)

[Philip Nienhuis]

When building dev-octave, during generation of docs, I get since (I 
think) yesterday or day before yesterday, many Glib-CRITICAL errors 
along the lines of:

:
  GEN      doc/interpreter/delaunay.txt

(process:28681): GLib-CRITICAL **: g_source_unref_internal: assertion 
'source != NULL' failed
:

Nevertheless the build continues fine. I suppose all bets are off for 
the figures in the generated docs.

Anyone else seeing this as well?

(This is on both my build systems, Mageia-5 and Mageia-6 linux)
