Package: epiphany-browser
Version: 2.29.91-1
Severity: important
when playing midi embedded in html, epiphany segfaults; not immediately,
but repeated refreshing provokes the crash. a quite minimal example url
that causes the effect is
http://vancouver-webpages.com/plugins/midi.html .
a backtrace from the core dump looks like this:

i have tried to reproduce the crash with midori, but midori just shows a
"couldn't be loaded. Plugin will handle load" error message in the
place of the player. (for a moment, though, it flashes the play
controls, so maybe it catches and handles the problem in the underlying
libraries?)
