No, the problem is with ivtv.  It's frame buffer ioctl definitions are
incorrect.  The problem only showed up recently because the kernel
headers use with Debian's latest libc are more strict.  Unfortunately,
fixing the definitions that myth uses breaks PVR 350 output because
they have to excatly match those in the ivtv driver and it hasn't been
fixed yet.  I notified the ivtv developers of the problem last week
but seem to have been soundly ignored.

For now, you can use the attached patch, but only if you don't use PVR
350 output.
