[TxMt] trouble with ui.rb

I already sent this message but publication is delayed for some reason - excuses in advance if the post will be repeated

After updating the Support folder, I am getting error messages in some of my routines which use ui.rb. But the errors seem produced by the lines in ui.rb like <<<<<<< .mine and ======= and similar ones. Strange thing, it seems like the errors are not related to my routines: a typical example:

/tmp/temp_textmate.LJOoCE:4:in `require': /Library/Application Support/TextMate/Support/lib/ui.rb:92: syntax error, unexpected tLSHFT, expecting kEND (SyntaxError) <<<<<<< .mine ^

Any help appreciated Piero
