Hello everybody. My technical specifications:

``` uname -a Linux SpSystem 4.10.0-38-generic # 42 ~ 16.04.1-Ubuntu SMP Tue Oct 10 16:32:20 UTC 2017 x86_64 x86_64 x86_64 GNU / Linux

Geany => Help => About. Geany 1.27 (collected Apr 17 2016 or later).

geany -V geany 1.27 ((collected Apr 17 2016 or later) GTK 2.24.30, GLib 2.48.0) ```

I installed plugins for Geany from the official Linux / GNU Mint repositories, everything is fine. I did this, because I needed to double the tags, for example in HTML. I did this with the plugin. Everything worked.

After a while I decided that I want to include the autocompletion of words. I enabled simple autocompletion through the settings, the first tick in the settings: Edit / Settings. In the settings window, select "Editor", "Autocompletion" tab, "Auto-complete code snippets" parameter).

In the future work suddenly, for the first time the editor closed. I propose it to an emergency. I ran it again. Everything worked, but when editing the file, if you get to the point where, in theory, the list with options for autocompletion may fall out, the program automatically ends without outputting any error, the window just closes (disappears).

I decided to disable autocompletion and the problem disappeared. Now I write the required code with my hands, without the possibility of an automatic add-on. The program is relatively stable. Paired tags are highlighted.

I do not know very well the terms from programming in English. I hope I clearly explained.

I decided to notify Geany developers about this issue so I am writing here. In some of the newest code editing programs (such as Atom), auto-completion usually works without lags and (or) critical errors. Geany should not fall behind, in my opinion. I hope the problem will be solved in the future.

I can provide almost any files in my system for additional information on this issue. I can conduct various tests at your request (Acceptable for me) when I have free time.

Thank you for watching.
