[Spice-devel] spice crashes

[Trebor Forban]

Hello Alon.

Thanks for your help.

This is what I get with the qemu debugging options:

qxl/guest-0: 1120951392537: qxldd: __PutBytesAlign
qxl/guest-0: 1120951398601: qxldd: __PutBytesAlign: done

qxl/guest-0: 1120951454964: qxldd: DrvTransparentBlt: done
(/usr/local/bin/qemu-system-x86_64:20029): SpiceWorker-ERROR **:
../spice-common/common/ring.h:83:ring_remove: assertion `item->next !=
NULL && item->prev != NULL' failed


I haven't recompiled with debugging for the stack trace yet; is it
still necessary, or does the information above suffice?

Regards,
TF
