bug#36118: segmentation fault in Totem

[Ricardo Wurmus]

Hi Laura,

thank you for the bug report.

These are not problematic.

Totem uses gstreamer, so the decoding of media files depends on the
installed codecs.  In fact, “/bin/totem” is wrapped with two variables
at build time: GST_PLUGIN_SYSTEM_PATH and GRL_PLUGIN_PATH.

Can you tell us what gstreamer plugins you have installed (these are
packages starting with “gst-”) and what values the GST_* environment
variables have?

With GST_DEBUG=5 (or a lower number) you should also be able to see what
gstreamer plugin is being selected.  Then we could try to narrow the
fault down to a specific plugin and its libraries.
