Package: libass5
Version: 0.13.5-1
Severity: important

After upgrading libass5 to 0.13.5-1, mpv routinely segfaults when
issueing commands that display some status information.  For example, it
always segfaults immediately on P (display progress bar) or PgUp/Down
(next/previous chapter), and is more-or-less likely to crash on other
commands as well.

I also get a slew of those messages whenever the bottom status/progress
bar is displayed:

  [osd/libass] [0x7f54500714d0]: Warning: no style named 'Default' found

Downgrading to 0.13.4-1 fixes both issues.


Here's the relevant backtrace; let me know if there's anything else that
could be helpful.
