Hello Patrik,
I just tried to collect some information and reconstruct
the given backtrace with some line information [1].

This gimp_text_tool_move_cursor leads to this upstream
bug reports [2]. Unfortunately all closed without result.

There are a few more upstream reports with g_utf8_get_char [3],
all with some non-latin characters, but all seem not
reproducible.

@Patrik, can you provide the text you wanted to enter?
Had it contained some "special" e.g. non-latin characters?
When you try it again, does it crash again?
If yes, maybe describe exactly the actions shortly before the crash?

Kind regards,
Bernhard

Hello Bernhard,

I think the text was the following [containing Czech characters]:

"Ahoj, já se jmenuji Sam a ty se jmenuješ jak?  Máš takový krásný
kožíšek, že Ti v něm musí být teď pěkně teploučko.  Ta bačkůrka v které
ležíš má stejnou barvu jako já."

When I tried again it did not crash as I have finished editing the
whole picture.

The actions taken: I have placed a text tool field over a picture
(backround) which has created its own layer (with text tool icon left
of the layer's name) where I have entered the text.  After the text
tool field was created I started typing the text and then it crashed.

Best regards,

Patrik

Dear Maintainer,

I can reproduce the segmentation fault with simple steps and no
non-latin characters on the text box. Steps:
 - Open GIMP
 - File > New
 - Select the Text Tool
 - Place it anywhere and hit any letter

I get a segmentation fault every time.

Here is the debug data spat out by GIMP. I'm not familiar with this,
it doesn't look exactly the same as that reported by Patrik. Please
let me know if I should open a new bug report instead. Please find
attached the output on the terminal when running the steps above, in
case it helps.


<!-- Copy-paste this whole debug data to report to developers -->
