Hi again,
I also reproduced the crash with Kurento's one2many example in the tutorial.
* FF 41.0.2 as presenter
* Chrome 46.0.2490.80 as viewer
After 17 minutes or so Kurento crashes with this error in syslog:
Nov 11 12:09:05 kurento01 kernel: [1593985.842165] KmsLoop[8300]:

libglib-2.0.so.0.4200.1[7fc3fc3af000+10a000]
And from media-server_error.log
