Please describe the problem:
eog doesnt escape the filename strings before inserting them into a GTK label (thus pango mark in the filename causes strange effects)


repro steps:
1. launch this command:
eog '<span font_desc="Monospace 30" foreground="#FF0000">string</span>'

another set of repro steps:
1. launch this command:
eog 'jack & jones'

Note 1: from the second example it should be clear that "normal" filenames can actually cause problems. In that second case eog thinks the "&" char in the filename is the beginning of the a pango markup entity. If you look carefully you can see that this also causes the <b></b> tags generated by eog to become visible as plain text.

Note 2: suggested fix, g_markup_printf_escaped()

Steps to reproduce:

Does this happen every time?
