rospack segfaults SIGSEGV on Groovy, Precise, 32b

[130s]

Originally asked here (http://goo.gl/JKJn3), and I can confirm this happens on my fresh-installed Precise 32 bit with Groovy (on VMWare Player). I've never seen this has happened on 64b machines.

After running

$ sudo rosdep init
$ rosdep update

the problem seems to have gone away. I did have to fix permissions in /etc/ros/rosdep as follows in order to run "rosdep update" successfully.

$ sudo chmod a+x /etc/ros/rosdep /etc/ros/rosdep/sources.list.d/
$ sudo chmod a+rx /etc/ros/rosdep/*

@azeey How did you install rosdep?

[dirk-thomas]

I am able to reproduce this on Quantal 64-bit with Groovy packages from shadow-fixed. The segfault happens when I remove the rosdep database under ~/.ros/rosdep/sources.cache. I will look into it and come up with a fix.

[azeey]

I assumed it was part of the standard installation. I'm using Ubuntu and I installed the full ros package. Rosdep must have been part of that package. I also installed python-rosinstall so it could be part of that. The error message I got when trying to build the package made seem like it was already installed.
