Resuming explains when a transcript is a symlink or couldn't be read.
What's wrong with this entry?
Anonymous. No account, no email.
What
Two new refusals when opening a stored conversation. A transcript file that is a symbolic link or not a regular file is refused, with advice to resume from the directory holding the real file. A transcript that could not be read at that moment now says so rather than failing generically.
Evidence
This conversation's file is a symbolic link or not a regular file, so it can't be opened from here
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
