I can reproduce this issue using the same build. A test survey is attached.

Mazi, I cannot reproduce this at all, neither with that specific release version nor with the latest Git version. Can you describe the exact steps to reproduce?

Carsten, I have created an account for you on my test server, you should have received an email at (email address removed).

When I try to import the attached survey at that system I get:
"Error: Failed to insert data[6]"

When I try to copy the "MASTER Template Test..." survey I get:
Error while saving: Array ( [qid] => Array ( [0] => Qid "2999" is already in use. ) )

At that system I manually updated from 2.05 RC5 to the stable version mentioned by copying all files and then overwriting /upload/* with the folder from the old RC 5 system.
Could that have caused the problem? Maybe I should have copied /upload/templates and /upload/surveys only?!

sth, what's your exact PHP version?

5.3.2 (sth is using on my server).

This seems to be a PHP bug as I could find no logical reason that it crashes out with duplicate database entries. For some reason the foreach loop gets messed up and the pointer is reset in the midst of the foreach - caused by the database insert. Makes no sense at all and does not happen on newer PHP versions.

2.05+ Build 140116 released

Error still exist when trying to copy a survey:
"Error while saving: Array ( [qid] => Array ( [0] => Qid "7709" is already in use. ) )"

I just updated to the latest 2.05 version, build 140125

Version 2.05+ Build 140204 released
