I would take a safe Maildir implementation over subtle (or sometimes catastrophic) data loss bugs any day. The one really serious problem I have with Thunderbird is that after being stung more than once, I feel like not only do I have to keep normal backups, I also have to retain old backups indefinitely, just in case a folder was corrupted silently a long time ago and I only find out months or years later when I need to search older messages.
