Bug 418290

Can confirm, but that's probably an issue in KIO (or maybe KFileMetaData, or Baloo).

Please provide the output of

$> balooshow -x <affected_file>.m4a

and attach /tmp/kfm_m4a.bin after running:

$> baloo_filemetadata_temp_extractor <affected_file>.m4a > /tmp/kfm_m4a.bin

Created attachment 126914 [details]
output of baloo_filemetadata_temp_extractor "09 Lights & Thunder.m4a" > /tmp/kfm_m4a.bin

This .m4a file was created using MediaCoderx64 on Windows with FAAC CODEC, if that is of any help.

Please check the output of
$>xdg-mime query filetype <path>

If that returns 'audio/...', try running

$> balooctl clear <path>
$> QT_LOGGING_RULES='kf5.*=true' balooctl index <path>

and check the output of balooshow again.

Also:
$> head -c 160 <path>  | hexdump -C

The clear command did not seem to work:

Older versions of baloo did not determine the mime type correctly under some circumstances, so that probably is the reason you ended up with a wrong mimetype in your DB.

Unfortunately, your DB shows internal corruption, so it is no longer possible to update it.

Please rebuild your DB by running
$> balooctl purge

OK, it seems to clear and index again now. I think my Baloo has also be updated. I am now on Frameworks 5.68.0.
