The theme itself doesn't write or create anything else outside of the database. Though, if you had installed via Cydia, it does keep track of the package and file it under the modmyi repository. However, I don't think that should have any effect on the theme itself...
I've been running on an SSH version as well. I'll do a clean install from Cydia to see if there are any issues.... as soon as Cydia updates...
Do you have a copy of 1.5.2? I'd rather just install that again and not rely on the database since it was working just fine for me previously.
