Bless crashes with X error if you try to open the file and right away, without clicking on any hex value, press ctrl+a to select all and press ctrl+c to copy.
How to reproduce:
Open bless
Drag-n-drop any sufficiently large file (100 KB is enough)
Press ctrl+a, ctrl+c
Bless crashes with X error
The bug does not happen if you first click anywhere in the hex viewer (to set cursor somewhere).
(bless:1107528): Gdk-ERROR **: 09:47:37.629: The program 'bless' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
(Details: serial 3815 error_code 3 request_code 18 minor_code 0)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the --sync command line
option to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
