Several GTK-apps not working anymore after update

[danteonline@gmail.com]

Hello there

Thank you for your reply
I'm sorry it took me so long to reply but I did not see your reply in a very 
long time :(

I gave iceweasel with your parameters a try, it started.
Also, the defoma-error is gone now, so the only thing left is that apps won't 
start and print me this error:


<error>

Pango-ERROR **: file pangofc-fontmap.c: line 438 (pango_fc_font_map_add): 
assertion failed: (fcfont->fontmap == NULL)
aborting...

</error>


I am now in the process of trying to downgrade libpango1.0-0 and 
libpango1.0-common, though this will probably not be a solution in the long 
run.

I will write to you again at any moment I figure out something new.

greets,
dante

What happens if you try to run

iceweasel --safe-mode

or

MOZ_DISABLE_PANGO=1 iceweasel --safe-mode

or

LANG=C iceweasel --safe-mode

?

/usr/lib/iceweasel/firefox-bin links against pango libraries which are
part of libpango1.0-0. If you decide to file a bug then it probably
should be filed against that package.

What output do you get if you run (as root)

/usr/bin/defoma-app -v update pango

> Any suggestions?

Try to downgrade libpango1.0-0 and libpango1.0-common.

If you did not deliberately override apt's package verification
mechanism then you should be safe.
