Import of words into dictionary fails

[Rob Managan]

I went to preferences, manage dictionaries, manage User Dictionaries, chose one I recently added, selected import list of words, used the past from clipboard button to get words into the text box, clicked the OK button and got this error.

The error report gave this info:

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.
