/usr/bin/mediascanner-service-2.0:6:__gnu_cxx::__verbose_terminate_handler:__cxxabiv1::__terminate:std::terminate:__cxxabiv1::__cxa_throw:std::__throw_logic_error

This is caused by a nullptr -> std::string conversion somewhere in extract_tag_info (the only match for the missing stack frame). But it is difficult to tell which conversion is the cause. There are two places where this could occur: (1) the tag name passed to the callback is NULL, or (2) a string tag value is NULL.

The second case seems more likely, so I've modified this code path in my taglib-extractor branch to add an extra NULL check. Lets see how that goes.

This bug was fixed in the package mediascanner2 - 0.111+16.04.20160225-0ubuntu1

  * Batch index updates during the initial scan in 10 second intervals
    (the same rate as invalidation notifications go out). This greatly
    reduces the IO overhead on initial startup, and is fairly safe now
    we have out of process metadata extraction.
  * Don't emit the InvalidateResults signal if a file was opened for
    writing and then closed, but not actually modified (LP: #1542175)
  * Favour the EXIF DateTimeOriginal tag over DateTime when extracting
    metadata from photos. (LP: #1468585)
  * Use taglib to extract metadata from Vorbis, Opus, Flac, MP3 and MP4
    audio files. Other formats will fall back to the existing GStreamer
    code path. (LP: #1536832)

  [ CI Train Bot ]
  * debian/libmediascanner-2.0-3.symbols: update to released version.
