Any chance you're able to reproduce this crash?
Comment 13 Michael Catanzaro 2015-04-16 22:12:08 UTC 
I see the result is GST_INSTALL_PLUGINS_SUCCESS which implies that GNOME Software was able to install all of the requested codecs before the crash occurred. Is that correct? If not, we have more than one bug here.

Guess: you closed the web page before the plugin installation finished? The code does not seem to be prepared for that. Alternatively, perhaps the video element was removed from the DOM by Javascript before the installation completed.

If you don't mind sharing, which web page did this happen on (to help reproduce)?
Comment 14 Peter 2015-04-17 05:41:01 UTC 
I open the Gnome Internet Browser.
Then I open the address "tagesschau.de".
Then I try to open a video with a not installed H.264-Decoder video codex.
Then the browser says that something went wrong with displaying the site.
