Hello, this is a known problem upstream, where torrentzip will change
permissions of the file it compresses, even locking itself out of being able to
write a file.
Currently I must use wine + torrentzip, which is less than ideal. I'm not a C
programmer, so would someone please look over this patch, taken from FreeBSD,
and see if it fixes the problem? tyvm!
Also see:
https://sourceforge.net/tracker/index.php?func=detail&aid=1415549&group_id=135285&atid=732451
and:
File permissions on Linux have different names: rename all
instances of 'S_ISTXT' in the patch to 'S_ISVTX' and
trrntzip will then compile.

Reproducible: Always
The provided patch does not compile.
Try this - it seems to work for me :

Thank you, that seems to do the trick! I'll continue testing.
