KITTY_ENABLE_WAYLAND=1 crashes with "Data too big for buffer"

[victortrac]

When I run kitty with KITTY_ENABLE_WAYLAND=1 kitty, I can get it to crash with this:

This results in kitty crashing with this error:

Error sending request: Argument list too long
Aborted (core dumped)

This is reproducible under both gnome-shell and sway 1.0-8.

I cannot reproduce in master with HEAD, so I assume this is already
fixed. If it is still an issue when building kitytfrom source, or after
the next release, feel free to re-open.

[XVicarious]

I get this on 0.14.2. I'm also on Arch, using Sway. I get it when a large amount of data is being output to the screen (like a program ending and dumping a log to the screen). I'll build from master to check that too. If there is any other information you'd like me to collect, please let me know.

[kovidgoyal]

I need some way to reproduce. Or at least a stack trace. because those error messages are not from kitty code.

[victortrac]

My issue was caused by setting a too-long PROMPT_COMMAND in my ~/.bashrc. I was setting the title to the entirety of my last command, which broke for very long commands (piping in some b64-encoded strings to base64, for example).

I know the backtrace isn't that useful, but I'm too lazy to rebuild wayland and kitty, and I probably won't be able to fix it anyways. hopefully you can reproduce with the provided command.
