Unable to launch seahorse

[Olivier Febwin]

When I try to run seahorse, I've these errors:

(seahorse:11732): Gdk-ERROR **: 14:45:20.702: The program 'seahorse' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadAlloc (insufficient resources for operation)'.
  (Details: serial 1008 error_code 11 request_code 130 (MIT-SHM) minor_code 5)
  (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 GDK_SYNCHRONIZE environment
   variable to change this behavior. You can then get a meaningful
   backtrace from your debugger if you break on the gdk_x_error() function.)

This issue occurs only on Xorg session (ubuntu 19.04).
No problem on Wayland session.

This will greatly help us in tracking down your problem.

Before using gdb do '$ export GDK_SYNCHRONIZE=1'

What version of Ubuntu are you using

it looks similar to taht upstream report, https://gitlab.gnome.org/GNOME/seahorse/issues/228

If this helps, I can prevent it from crashing if I use GTK_DEBUG=no-pixel-cache OR GDK_RENDERING=recording with some caveats.

GDK_RENDERING=recording works but has lots of rendering artifacts.
GDK_RENDERING=image does not crash but Passwords/Login does not render. Certificates/Secure Shell/PGP Keys render fine.

If I use GTK_DEBUG=no-pixel-cache everything seems to work properly.

I agree with the link above that it seems related to the number of passwords in the Login store.

This also impacts other stores (mine only crashes when I switch to GPG keys).
