Hello,
the problem does not seem to occur any more with
gstreamer1.0-plugins-bad 1.6.1-1+b1 and iceweasel 38.4.0esr-1.
Do you have any specific packages for me to test?
Just a normal jessie installation without installing things from other
sources, including sid :) It is definitely fixed since gst-plugins-bad
1.5.X, it's just not clear if the actual bug also exists in jessie or
not (and if it doesn't, the fix will also have no effect for people who
mix their packages with ones from other sources).
Hello,
it is not fixed, alas. The following SIGSEGV backtrace is with
gstreamer1.0-plugins-bad 1.6.1-1+b1 and iceweasel 38.4.0esr-1. Such
crashes are rarer, but they do occur:
