Title:
qemu segfaults after spice update with bochs-display
Status in QEMU:
New
Bug description:
Description:
qemu segfaults after latest spice update with bochs-display.
Downgrading spice solves the issue. Switching to qxl-vga and/or
virtio-gpu also works even with new spice.
Additional info:
* package version(s)
spice 0.14.2-1 (0.14.0 is unaffected)
qemu-headless 4.0.0-3
* config and/or log files etc.
