Woah, yes I have! I am using GDAL trunk ("1.8.0") to churn through some
imagery, and noticed strange black lines through some of the output. In my
initial investigation I couldn't find them in the source data. I am glad you
posted, because I was going to have to track this down eventually and my large
source data makes that a slooooow process.
