In Calc, select cells then try to "Paste special" with Transpose.
I got "There is not enough space on the sheet to insert here." message. When I switch Transpose off it is possible to insert special.
Affected version: 3.4.0, was good in 3.2.2.
Tested on Linux OS (Ubuntu)

RC2 is bit by bit identical with release version, so separate items in the version picker are useless. Changes have been discussed with Michael Meeks.
