Oh, I am sorry again. It should be "/usr/bin/anki", not just "anki".
Please try this:

- gdb python3
- (in gdb) run /usr/bin/anki
- wait until anki exits (this run is needed for gdb to pick up Gdk symbols)
- (in gdb) b gdk_x_io_error
- (in gdb) run /usr/bin/anki
- wait until the breakpoint is activated
- (in gdb) bt
- attach the output here

This time I have actually tested that the breakpoint is set successfully :)

I am not promising this will be the last experiment. If the error turns out
to be related to some other libraries like Qt, I will ask you to install debug
symbols for these libraries and obtain the backtrace again.
