A clear and concise description of what the bug is.

If I leave the GZDoom game selection window open for a short time, it crashes and the pictured error appears.

I played through The Ultimate Doom's E1M1 without issues, so this does not appear to be a problem that occurs during games. Additionally, it seems to occur only when the game selection window is left idle, as it has not happened while I'm actively clicking things within the window. Then again, the amount of time before the error appears is not consistent — sometimes it happens within a couple of seconds, and other times it takes a minute even if I'm not touching the window — so maybe it's just a coincidence that I've seen it only when leaving the window idle.

I have tested only the copy of GZDoom that I installed from DRD Team's Debian repo, which I updated to g4.12.1 yesterday. I would test the "portable" Linux release as well, but it looks like the portable version 4.12.1 has not been published yet.

Steps to reproduce the behaviour.

Explain how to reproduce

1. Run gzdoom to open the game selection window.
2. Wait.

Your configuration

Happens with default configuration (after renaming gzdoom.ini and letting GZDoom make a new one).

Provide a Log

If I run gzdoom from a terminal and wait for the error to occur, no additional errors are printed to the terminal when it does.
