Description Rafael Lukas Moe 2004-10-02 05:26:25 UTC

When I try to start gimp-2.0.4 at all it starts to load some files and then
suddenly crashes. The output says something about pango, but I'm not sure what
the problem is. I've tried both 1.4.0 and 1.4.1 version of pango, where neither
really helped at all. I also tried to re-emerge gimp-2.0 with both version, which
aslo didnt help at all.


Reproducible: Always
Steps to Reproduce:
1. start a term 
2. start gimp by: gimp-2.0
3. crash on startup and error messages

Actual Results:  
The output I get from the crash is the following: 

"** (gimp-2.0:4997): CRITICAL **: file pango-coverage.c: line 171
(pango_coverage_get): assertion `coverage != NULL' failed

** (gimp-2.0:4997): CRITICAL **: file pango-coverage.c: line 138
(pango_coverage_unref): assertion `coverage != NULL' failed

(gimp-2.0:4997): GLib-GObject-CRITICAL **: file gobject.c: line 1561
(g_object_ref): assertion `G_IS_OBJECT (object)' failed

** (gimp-2.0:4997): CRITICAL **: file pango-engine.c: line 68
(_pango_engine_shape_shape): assertion `PANGO_IS_FONT (font)' failed
gimp-2.0: fatal error: file shape.c: line 75 (pango_shape): assertion failed:
(glyphs->num_glyphs > 0)"

It repeats itself all the way through with line 171 and 138 until the end where
it gives out on line 1561 and 68.

Expected Results:  
gimp-2.0 should have loaded as expected and the program should have been executed
successfully.

are you using any other gtk+ applications ? does gtk-demo also crash ? What are your locale settings ?

Comment 2 Rafael Lukas Moe 2004-10-02 12:17:22 UTC

Yes, I mainly use GTK+ applications, both GTK+1 and GTK+2. Some of me favourites
are xmms, sylpheed and gaim, just to mention some. gtk-demo works completely fine.

also, I'm not sure what locale settings are, but they do sound familiar. how do 
I check them?

Comment 3 Henrik Brix Andersen 2004-10-02 12:31:08 UTC

You paste the output of the 'locale' command here :)

Comment 4 Rafael Lukas Moe 2004-10-02 13:11:29 UTC

Sure, here's the output:

LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=

Comment 5 Henrik Brix Andersen 2004-10-02 13:41:35 UTC

Could you please verify that the problem exists when using the following command:

export LANG=en_US.UTF-8
gimp

Comment 6 Rafael Lukas Moe 2004-10-02 14:16:15 UTC

It does not, and therefore I declare this bug as FIXED (hopefully!).

Thank you very much for solving this problem for me. The only thing that got me 
worrying is why I suddenly got this problem at all, because gimp-2.0 used to
work perfectly fine before.

Aslo, what value should LANG really have and how do I set it for good (instead of 
running the command everytime after a boot)?

Comment 7 Henrik Brix Andersen 2004-10-03 14:12:44 UTC

You can do the following:

echo LANG="en_US.UTF-8" > /etc/env.d/50i18n
env-update

The first two letters is the language code (en = English), then comes an underscore. The following two letters are the country code (US = USA). What comes after the dot is the encoding (UTF-8).
