gnucash-1.9.1 startup: "ignoring invalid short option" even when no options given

[Thomas Klausner]

Hi!

With 1.9.1, every time I start gnucash, I get a number of lines on
the console of the form:

$ gnucash

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\u001c' (28)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\xec' (-20)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\xff' (-1)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\u0014' (20)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '-' (45)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\xe8' (-24)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\xeb' (-21)

(process:489): GLib-WARNING **: goption.c:1672: ignoring invalid short option '\u0008' (8)


I don't give gnucash any arguments (it's not an alias or anything).
What's happening here?
