Bug#702129: libgtksourceview-3.0-0: gedit crashes with "Defaults" language

[Stijn van Drongelen]

Package: libgtksourceview-3.0-0
Version: 3.4.2-1
Severity: important

Hi,

I just noticed that gedit is very easy to crash by performing the following
steps:

1. Start gedit.
2. Switch the language to "Defaults". (corresponds to
/usr/share/gtksourceview-3.0/language-specs/def.lang)
3. Type any letter.

The same happens when trying to render an existing document with this language.
The following is dumped to stderr by gedit before the window disappears:

    **
    GtkSourceView:ERROR:gtksourcecontextengine.c:5487:update_syntax: assertion
failed: (state->context != NULL)

I'm marking this as important, since I don't think a library should be able to
die due to the contents of a configuration file.

Kind regards,

Stijn van Drongelen
