Crash when browsing a gallery with arrow keys
When going through a gallery of images with the left/right arrow keys, Ristretto sometimes crashes randomly with the following error:
[xcb] Unknown sequence number while processing queue ─╯
[xcb] Most likely this is a multi-threaded client and XInitThreads has not been called
[xcb] Aborting, sorry about that.
ristretto: xcb_io.c:269: poll_for_event: Assertion `!xcb_xlib_threads_sequence_lost' failed.
I'm using Arch Linux with the latest updates. I tried Ristretto 0.12.1 and the latest master, but both of them crash with the same error.
