0.44.1 works fine on my G4 running 10.4.7, but it had some quirks.
- The disk image I downloaded from SourceForge's Virginia mirror came out corrupt. Fixed by downloading again from another mirror.
- On first run, nothing happened for a short while. Then I got a dialog asking if I wanted to rebuild the X11 font cache to avoid potential problems. I said yes, it took a while, then asked me to restart Inkscape.
- On second run, it took a LONG time to start. If you're not sure if Inkscape is running, run /Applications/Utilities/Activity Monitor and look for the "inkscape-bin" process.
- On third run and after, it came up very quickly. No further issues.
