<p>OS: Xubuntu 16.04<br>
Geany version: geany 1.32 (built on Dec 24 2017 with GTK 2.24.30, GLib 2.48.2)</p>
<p>Crash output:<br>
The program 'geany' received an X Window System error.<br>
This probably reflects a bug in the program.<br>
The error was 'BadWindow (invalid Window parameter)'.<br>
(Details: serial 51873 error_code 3 request_code 18 minor_code 0)<br>
(Note to programmers: normally, X errors are reported asynchronously;<br>
that is, you will receive the error a while after causing it.<br>
To debug your program, run it with the --sync command line<br>
option to change this behavior. You can then get a meaningful<br>
backtrace from your debugger if you break on the gdk_x_error() function.)</p>
<p>How to reproduce.</p>
<ol>
<li>Open any big text file. You can make one with the following bash script:<br>
<code>for i in {1..1000000}; do echo 1234567890 >> big.txt; done</code></li>
<li>Copy content of this file to clipboard (ctrl+a, ctrl+c).</li>
<li>Create a new file. Do not paste copied data.</li>
<li>Open save dialog (ctrl+s).</li>
<li>Start typing name (you can hold 1) or select target file several times (for me it always crashes before I select files 10 times). Geany crashes.</li>
</ol>
<p>I built geany from github with <code>CFLAGS=-g</code> and tried to debug it with gdb. <code>bt</code> did not show anything.<br>
I will give additional info if you need it.</p>
