This shounld be not occure. At all.

btw, this bug occur not strictly in "ePub Extended Metadata" plugin, but in a common libs used on my other plugins, so can you install them to see if it happend too: Comments Cleaner and Mass Search/Replace (we will keep the conversation going here)

In the meantime, can you also test this version to see if it work now?

With the test version I am not getting a crash on export, but now this on import:
calibre, version 9.7.0
ERROR: Cannot add books: Failed to add some books, click "Show details" for more information.

Worker process crashed while executing job
Traceback (most recent call last):

File "multiprocessing/connection.py", line 447, in _recv_bytes
File "multiprocessing/connection.py", line 416, in _recv
EOFError

(same as before, its just the popup from Calibre, no log files to be found)

If i disable the extended metadata import it works fine.

Tried Comments Cleaner, it works fine. No crash and I see the changes.

Both are enabled in the settings.

I've got some issues with the current release version/ When I did an import on an ePub2 eBook, I got the following error.

ePub Extended Metadata (Writer) is disabled. I did not not disable it. And I am unable to configure any columns. I created a subtitle column and I cannot specify it. Debug mode shows nothing wrong.

urgh.
Okay, that it, I'm out sorry.
All your error come outside of my plugin and are the result of a some how serious error in Calibre, so way above me, sorry.
Will still release the version with the fix, but all that is now out of my hand.

No, worries. Thanks for checking it out! And your fast responses. If I find a fix Ill update (for the case someone else has the same issue)

I still cannot customize the titles section. I created a column for subtitles and I cannot use it.

Are you sure that the column is a "Lont text, like comment, not in the tag browser" with the subsetting "Short text, like title"?

Yes I have the column set as long text.

Set as "long text" is not enough, you need to go into the column setting and set the subtype/format to "Short text, like title".
Without that, the column is considered a comment and is therefore excluded.

If i try to add an epub with the plugin installed i get:

calibre, version 9.7.0
FEHLER: Hinzufügen der Bücher nicht möglich: Einige Bücher konnten nicht hinzugefügt werden. "Details anzeigen" anklicken für weitere Informationen.

Worker process crashed while executing job
Traceback (most recent call last):
File "multiprocessing\connection.py", line 338, in _recv_bytes
BrokenPipeError: [WinError 109] Die Pipe wurde beendet

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
File "calibre\utils\ipc\pool.py", line 106, in recv
File "calibre\utils\ipc\__init__.py", line 20, in eintr_retry_call
File "multiprocessing\connection.py", line 222, in recv_bytes
File "multiprocessing\connection.py", line 353, in _recv_bytes
EOFError

after removing the plugin everything works

[un_pogaz]

Can you restart calibre in debug mode "Preference -> Restart in debug mode" adding the epub, and after that the error occur, close calibre en send me a copie of the file open by calibre?
Thanks.

[ZackMuc]

Attached is the logfile

[un_pogaz]

Thanks and I'm sorry.
Is a way too complex error that I can't resovle remotly.
Can you send me the book that cause this issue? In hope this isn't a problem specific to Windows.

[ZackMuc]

Can you send me a PM with your email?

[un_pogaz]

So good new: I have the bug \o/
I will can work to fix it, thanks.
(on the other hand, no promise on how long it will take me)
