<p>+1 , same issue here that seems only started happening recently (I keep upgrading whenever there is a new version update :)</p>
<p>This happens when using Geany to open a loooong text file (like mine had 3MB+) and then if you do some search and/or copy/paste/cut operations.</p>
<p>Geany-INFO: /home/lylew/path/to/my/java/thread/dump/file.out : None (UTF-8)<br>
[New Thread 0x7fffd6e0d700 (LWP 17653)]<br>
[Thread 0x7fffd5e0b700 (LWP 17650) exited]</p>
<p>(geany:17597): Gdk-ERROR **: 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 24765 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>
