[Gtranslator-devel] (GtkEditable???) will crash

[Peeter Vois <Peeter Vois mail ee>]

Hi,

First: Happy New Year!

Some time ago I sent a message into gtk-app-devel list showing a bug in
GTK library, but nobody will iterest :(. This is maybe the gtk1.2 is 
thrown away (but new one is not ready yet).

Since there is a cruel bug in gtk_text (or am I wrong), I am thinking that
the syntax highlighting should be turned off by default in the stable
release.

Hi,

I just started new project and ran into enormous problem. I can not find
error from my code, I'll search further. The backtrace will show that
library function will crash.

The project itself: http://my.tele2.ee/vois/gtexedit-0.1.tar.gz

How to make this problem appear:

write:
\begin{equation}
bla bla bla
\end{equation}

delete (backspace):
\begin{equation}
        <-^
bla bla bla
\end{equation}
