There are two probable issues: - there was a crasher bug with videoVLC, that was (introduced and) fixed recently - there seems to be some glib incompatibility with *another* external. I dont know if this is fixable at all.
To detect which of the two issued you have do: - make sure you have the latest Gem from git - try loading Gem/videoVLC without *any* other external (and then add externals until you find the culprit)
Yes, I have the latest Gem from git. It is a problem between gem_imageMAGICK.so and gem_videoVLC.so. When I add gem_imageMAGICK.so in the Gem directory (where gem_videoVLC.so is already in place), Pd crash at startup. ++

I will try with a new build of Gem with : $ make clean $ git pull $ aclocal $ ./autogen.sh $ ./configure $ make And I keep you informed. ++

I still get the Pd crash (Ubuntu 14.04). Always between gem_imageMAGICK.so and gem_videoVLC.so.

`$ dpkg --list | grep libvlc` and `$ dpkg --list | grep magick` give me the same as Jack but I don't have any crash.
The line #27 of the backtrace says :
~~~~ <error reading variable: access outside bounds of object referenced via synthetic pointer> ~~~~
Could this be the cause of your crash ?

urgh, this is slightly ugly to debug.
both vlc and ImageMagick have plugin-systems, which get initialized during initialization of Gem's plugin system, and which seem to trigger a conflict.
just to imagine:
- Pd starts, and loads *Gem.pd_linux* via `dlopen()`. - *Gem* searches for plugins and finds and loads *gem_imageMAGICK.so* via `dlopen()`. - *gem_imageMAGICK.so* initializes *ImageMagick* - *ImageMagick* searches for plugins in `/usr/lib/.../ImageMagick-6.7.7/modules-Q16/` and loads them via `dlopen()`. - *Gem* searches for more plugins and finds and loads *gem_videoVLC.so* via `dlopen()`. - *gem_videoVLC.so* initializes *libvlc* - *libvlc* searches for plugins in `/usr/lib/vlc/plugins` and loads them via `dlopen()`.
the crash seems to be related to `glibc` (when (re)initialized by the qt-plugin for vlc's gui)
