I'm trying to use "melt" (media-libs/mlt-0.7.2) and get the following. Kdenlive uses melt for rendering the final video file. I just used this feature (in exactly the same way) successfully about a month ago. I honestly don't know what has changed. Yes, I've tried recompiling: glibc nvidia-drivers and the relavent packages from "qdepends mlt". me@aragorn ~ $ melt *** glibc detected *** melt: free(): invalid pointer: 0x087ed270 *** =======

I have been able to "fix" this issue. I was using a different version of media-plugins/frei0r-plugins found here: https://bugs.gentoo.org/show_bug.cgi?id=340793 The version 1.3 causes this mlt error. When I downgrade frei0r-plugins to the portage version of media-plugins/frei0r-plugins-1.1.22-r2, melt works fine. I don't know what you want to do with this bug now that I've found this out. M.
seems fine here with mlt-0.7.6 and frei0r-plugins-1.3 from the tree, please reopen with a backtrace if this is still an issue for you
