[mythtv-users] mythweb and mythfrontend preview images missing

[Peter Abplanalp]

hi all,

i just recently began having issues with thumbnails.  both mythweb and
mythfrontend preview images are not being created.  mythbackend
reports the following when trying to generate previews:

that is the output for 2 of the recordings.  it happens for all the
recordings.  of particular interest is the 'Illegal instruction'
output.  i've tried running the command as mythtv from the command
line and it ends with the same 'illegal instruction'.  i've checked
the permissions and they are fine.  things get recorded and play back
fine as well.

output for mythbackend --version is:
