Corrupted zip archive

i found a bug in the archive handling function.
creating a new file inside a zip file and then renaming it corrupts the archive.
doing a second operation after that outputs an error message

I can't reproduce that problem.

Please give exact step-by-step instructions on how to repro it. (e.g. How is the new file created, and what is the second operation?)

i use this file:
then i create a new file with Alt+F which uses this command: FileType NEW=.txt
then i renamed it with F2 which uses this command: "rename INLINE=single ADVANCED PRESET=_Erweitert"
then i leave the archive and go back in. now it is empty
if i did another operation without leaving i would get an error

Thanks. With that archive I can reproduce it (but not with an archive created by Opus).
