You did not include a backtrace, but the description appears to be equivalent to the issue already reported in ticket #12888 which you can presumably validate by applying the patch in that ticket to confirm the bug goes away (that patch is not a fix, but could verify it is the same bug)

It seems to be same bug as ticket #12888. I compiled branch fixes/0.28 from github, configured with ./configure --prefix=/home/mythtest/build --enable-libzvbi --compile-type=profile and got same error. Backtrace attached. (gdb.txt). I made change suggested in #12888 and a png file was produced with no error, but was not a correct preview.
