unexplained crash inside GTK since +- 10 days

[Stan Pinte <stan sauvages be>]

Dear all,

we are having random, unexplained crashes in GTK, used from guile, with
the following outputs:

In expression (g-main-loop-run (g-main-loop-new)):
GLib-GObject: g_object_ref: assertion `G_IS_OBJECT (object)' failed

or

In expression (g-main-loop-run (g-main-loop-new)):
GLib-GObject: gsignal.c:2133: signal id `32' is invalid for instance
`0xa21a820'

Any idea of what we could do to track that down?

Thanks in advance for your help,

Kind regards,

Stan.
