Traceback on parsing email without info which email caused it.

[mwdg]

I'm deduping a large maildir.

Command line:

mdedup -n -S 0 -C 0 -a move-selected -e maildir -E ~/mail/Maildir/.GMAllMailNonDupe -s select-oldest  ~/mail/Maildir/`

Output ends with:

Check mail differences are below the thresholds.
Select all mails sharing the oldest 1299180509 timestamp...
warning: Skip set: all 5 mails within were selected. The strategy criterion was not able to discard some.
◼ 7 mails sharing hash faad932b06e1bed2520658105bcae3d483acf05fd605db23f365adc6

It looks to me like there's a defective email, but how am I supposed to figure out which one?

Hello and thank you for your report. Do you not get error messages in Phase 1 like I do in #155? What is the output of mdedup --version?

The -H switch looks like something you might want to try to only compute the hashes, then grep for the hash faad932b06e1bed2520658105bcae3d483acf05fd605db23f365adc6 you were given to find out which files are affected.

I tried adding the -H switch to the same command line (hope that's valid):

mdedup -n -H -S 0 -C 0 -a move-selected -e maildir -E ~/mail/Maildir/.GMAllMailNonDupe -s select-oldest ~/mail/Maildir/

It crashed with this:

For the original problem, I'm not getting any errors or warnings in Phase 1:

● Phase #1 - Compute hashes and group duplicates Use [date, from, to, subject, mime-version, content-type, content-disposition, user-agent, x-priority, message-id] headers to compute hashes. Hashed mails [####################################] 166405/166405

Hello and sorry for the delayed response. Would you mind to update your installation to the latest release (for example via pip3 install -U mail-deduplicate) and let us know if you can still reproduce the issue there?
