Program terminates on context menu copy

[Tomasz Zeman]

The program terminates after copy of image using context menu.

This happen after copy of jpeg file, and one succuess paste into KolourPaint. Second attempt generated this error:

GLib-CRITICAL **: Source ID 383 was not found when attempting to remove it at /usr/bin/shutter line 7262.
The program 'shutter' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadWindow (invalid Window parameter)'.
  (Details: serial 23028 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.)

Are you possibly using the Shutter snap?

[Tomasz Zeman (namezis)]

No. It is the one installed with Linux Mint 19.3 Cinnamon.

Looks like it is a duplicate of https://bugs.launchpad.net/shutter/+bug/1880203

[Tomasz Zeman (namezis)]

Ok, let try this:

$ perl -MDebug::LTrace='*' ./shutter

I opened the image called "Selection_999(283).png".

It is a jpeg.

All these evt_tab_button_press are mouse clicks on the image. The program worked fine.

Then copy from the context menu, followed by crash.

It is always around the function: main::fct_show_status_message()

I do not know much about perl or perl+Glib programming, but from this link:

https://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html#g-source-remove

we have:

It is a programmer error to attempt to remove a non-existent source.

More specifically: source IDs can be reissued after a source has been destroyed and therefore it is never valid to use this function with a source ID which may have already been removed. An example is when scheduling an idle to run in another thread with g_idle_add(): the idle may already have run and been removed by the time this function is called on its (now invalid) source ID. This source ID may have been reissued, leading to the operation being performed against the wrong source.

Glib::Idle->add() is called in several places. Could there be a problem?
