I'm trying to upgrade a script-fu script (written by someone else) that worked in Gimp 1.2 to Gimp 2.0 after upgrading the operating system from Redhat Enterprise LInux AS 2.1 to RHEL AS 4. The script is supposed to make a bar graph from an input file. When I ran it from the Script-Fu menu, it didn't give any errors, but it didn't produce anything, either. I entered the main function call in the Script-Fu console, and the following error message appeared on the command line:

(script-fu:10545): Gtk-CRITICAL **: file gtktextbuffer.c: line 557 (gtk_text_buffer_emit_insert): assertion `g_utf8_validate (text, len, NULL)' failed

Again the graph wasn't produced, and there weren't any errors in the console. Has anybody encountered this problem before? Is there something wrong with my GTK installation? This Gimp version is the default that came with the operating system.

The error is only occurring when get-text is called on a string that contains special characters like the degree sign for latitude and longitude. I have no idea how to fix this!

Why don't you look on the GTK mailing list for info on this and maybe post a question there.

Peace...
