Rhythmbox timeout failure

Hey folks, anyone failing to run Rhythmbox 3.4.8 under Gnome 48? I receive a critical timeout warning, but no additional details. Running Rhythmbox in debug mode is equally unhelpful:

bill.valaski:~> rhythmbox --debug
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib64/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
libva info: va_openDriver() returns 0
(09:58:22) [rb_debug_init_match] …/lib/rb-debug.c:255: Debugging enabled

(rhythmbox:117420): Rhythmbox-CRITICAL **: 09:58:47.158: Timeout was reached

Any thoughts on how to get this fixed? Thanks!
Bill

Just a short follow-up on this issue - an update I applied this week to OpenSuse Tumbleweed included changes to GStreamer Multimedia Codecs - Base. Since the update Rhythmbox now operates normally again.
