Problem with "export" and progress indicators

The following script will not export my records if I use a progress indicator. If I remove any use of the progress indicator, it works as expected. Odd!

using terms from application "DEVONthink Pro"
	tell application "DEVONthink Pro"
			set theRecord to get record at "/Writings"
			show progress indicator "Exporting Writings" steps 2
			step progress indicator "Clear existing Writings"
			tell application "Path Finder"
				delete "Users:johnw:Sites:johnw:Writings"
			end tell
			step progress indicator "Export Writings"
			export record theRecord to "/Users/johnw/Sites/johnw"
			step progress indicator "Upload Website"
			do shell script "/sw/bin/sitecopy -u johnwiegley"
			step progress indicator "Synchronize Website"
			tell application "Safari"
				make new document at beginning of documents
				set URL of document 1 to ""
			end tell
			hide progress indicator
		on error error_message number error_number
			if the error_number is not -128 then
					display alert "DEVONthink Pro" message error_message as warning
				on error number error_number
					if error_number is -1708 then display dialog error_message buttons {"OK"} default button 1
				end try
			end if
		end try
	end tell
end using terms from

Thank you for the bug report, the final release of v1.3 will fix this.
