After the latest update, whenever I run ‘mate' from the command line, I get this message: 'Can’t launch TextMate.app (error -10810)’. Once I start Textmate, if I uninstall the command line support, and re-enable it, ‘mate’ works until the next reboot.

The problem is with your launch services database, basically a lookup in the system’s database (by mate) does not reveal where TextMate.app is located on your system.

To reset the database run this command (one line):

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed {,~}/Applications{,/Utilities}

If you have applications in other locations, you can add the paths to the end of the line.

After you reset the database, I suggest you launch TextMate via Finder, as I think this marks the application as having been explicitly launched by the user, so it won’t warn when indirectly opening TextMate by e.g. opening a text file.
