crash in gst_plugin_scanner from port:gstreamer010

[RJVB (René Bertin)]

I've started running into a crashing from gst_plugin_scanner when starting digikam, after rebuilding port:opencv with different variants.

The crash disappeared when I reactivated the original version and couldn't be attributed to a particular variant, so I thought maybe I had to rebuild gstreamer010 . After doing that, gst_plugin_scanner crashed even with the old opencv version.

The crash is in dup2, which is called to redirect stderr to stdout:

     /* Dup stderr down to stdout so things that plugins print are visible,
      * but don't care if it fails */

given that 2nd line I first tried to close(2) to close stderr, but that also crashes. Doing nothing (out-commenting the dup2 statement) seems to be the workaround, which is not incompatible with the intended behaviour as described in the comment.

The crash cannot be reproduced starting gst-plugin-scanner from a terminal, so it is related either to the way digikam starts the tool, or to the fact that it is started from an application in an app bundle.

NB: we're talking about the same opencv *release*, but different installed *versions* ;)
