Not sure how else I can explain this but here goes.
Yes I had problems previously with running inkscape.tcz previously on TC 2.8 in fact on TC 2.7 also.
I did 3 separate clean installs to TC 2.7 and 2 clean installs to TC 2.8 to check it wasn't an install problem but each time I had the same problem. Please see
http://forum.tinycorelinux.net/index.php?topic=4633.0 and
http://forum.tinycorelinux.net/index.php?topic=4647.0But I found it was a dependancy issue which I could work around. It still needed fixing IMHO.
Okay so now, as I say above, I replaced the bzImage and tinycore.gz files of v2.8 with those of TC 2.8.1
I then used Tools>Update_Extensions and it stopped with the message that gcc_libs was missing.
It froze the system and I had to do two hard reboots to get back to a desktop. When I did that I did Tools>Update_Extensions again and it stopped updating again but I noticed it stopped whilst trying to update Inkscape. So I deleted the inkscpae.tcz files in /tce/optional and rebooted. I did Tools>Update_Extensions yet again and it updated all remaining extensions this time.
So I assume the new inkscape.tcz doesn't like being updated the Tools>Update_Extensions way, unlike all the 20 other extensions I have.
Hope that is clear but please tell me specifically if any of this is unclear.
Thank you
