Bug 445620

STEPS TO REPRODUCE
0. Set up network samba share using systemd .automount and .mount units, working fine with network music directory mounted locally as (not important so I make something up here) ~/me/music/.
1. cmd: balooctl resume
2. cmd: balooctl status shows the indexing is stuck with files left to index - ie indexing appears frozen at a particular flac file after successfully indexing x1000's of other flac files.
3. after a while a TagLib error is automatically printed at the command line.  The error seems to vary slightly each time but all errors are similar to "TagLib: MPEG::Properties::read() -- Could not find a valid last MPEG frame in the stream. "
4. interestingly, the supposed successful indexed flac file metadata of the sucessessfully indexed flac's do not show up in (eg) "artist" or "album" columns in Dolphin.

OBSERVED RESULT
- baloo stops indexing, stuck with a remaining number of files to index when balooctl status is entered in terminal
- metadata from flac files reported by balooctl status as successfully indexed do not show up in (eg) "artist" or "album" columns in Dolphin.

EXPECTED RESULT
baloo should finish its indexing work and following finish should return the following with the command  "balooctl status":
Baloo File Indexer is running
Indexer state: Idle (Powersave)
Total files indexed: (some number)
Files waiting for content indexing: 0
Files failed to index: 0
Current size of index is (some number) MiB

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:   5.15.2-zen (Garuda Linux distribution of Arch Linux)
KDE Plasma Version:  5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2
taglib version: 1.12-1 from archlinux "extra" repo

ADDITIONAL INFORMATION
I have tried this under both wayland and x11 with the same/similar taglib error results.  This bug is particularly problematic for Elisa music library collation as it relies heavily on the baloo backend, and is the reason why I'm here.  I will submit this bug under Elisa also, being such a critical part of that program.
