[TxMt] Ruby error in GTDAlt bundle when adding a date to an action

[infoarts at gmail.com]

When I try and add a date to an action in the GTDAlt bundle, I get the
following error:

--
/usr/local/lib/ruby/1.8/date/format.rb:230:in /bin/bash: -c: line 1:
unexpected EOF while looking for matching `''
/bin/bash: -c: line 3: syntax error: unexpected end of filestrftime'
	from /usr/local/lib/ruby/1.8/date/format.rb:201:in /bin/bash: -c:
line 1: unexpected EOF while looking for matching `''
/bin/bash: -c: line 3: syntax error: unexpected end of filestrftime'
	from /usr/local/lib/ruby/1.8/date.rb:1343:in
--

Any clues on how to sort this out?
