Logging function call missing on 100%

[MoritzWillig]

So I was able to run something recently with a 14-band image, numsegments = 300 and compactness = 0.01

However, the SNIC doesn't seem to run till 100%

processed 98.28%
processed 98.81%
processed 99.34%
processed 99.87%

What could be a reason? Also, in my final image, I'm not getting many closed polygons. What could be a possible fix here. This doesn't happen for simple rgb png file
