F29 Kernel / Nvidia VDPAU bug?

After updating to F29 I get a hard lock on mythfrontend when I try to start playing back a recording. Looking through the log I saw this: [14099.229428] BUG: unable to handle kernel NULL pointer dereference at 0000000000000080 [14099.229434] PGD 16f53f067 P4D 16f53f067 PUD 22270b067 PMD 0 [14099.229440] Oops: 0000 [#1] SMP NOPTI [14099.229443] CPU: 0 PID: 11830 Comm: mythfrontend Tainted: P OE 4.19.3-300.fc29.x86_64 #1 [14099.229446] Hardware name: Gigabyte Technology Co., Ltd.
