Today I noticed a new bug; persisted TextMorphs were always materializing with the default font.
TTFontDescriptions are canonicalized into a class var, with each image potentially having a different set of fonts. Magma doesn't reinvent the wheel; employing the built-in System behavior, the DiskProxy mechanism to, upon materialization, lookup the font by name and, if not present, use the Default.
The problem was two-fold. First, "Ma object serialization" was incorrectly looking it up by #fullName, instead of #name, causing the Default font to always be used. Second, the base Squeak 3.9 image somehow lost all but one of the cached TTFontDescriptions from 3.8. The attached file-in will simply restore these (from allInstances, of which there are exactly 10 in 3.9).
After these two fixes, my TextMorph fonts are now correctly being identified and used.

This will, of course, be integrated into r41.
