SUMMARY

When writing very small ISOs and data projects (to DVD+RW media in this case), k3b will often show wildly wrong information about how much data has been written. By very small, I mean less than a megabyte, and I have seen this with multiple different images/projects.


STEPS TO REPRODUCE
1. Create a very small (< 1MB) ISO or data project.
2. Burn to media (tested with DVD+RW, possibly affects others).
3. See strange numbers for "data written".

OBSERVED RESULT

Numbers for data written are very strange and nowhere near the actual size. See attached screenshots. I suspect this is maybe some kind of race condition that occurs when the write takes less than a second (or something around that amount of time).

EXPECTED RESULT

Numbers for data written are accurate.
