game crashes when entering world

[donkyhotay]

I run ubuntu 64bit feisty and have been having issues with regnum. When I load the game I recieve the error

Gtk-WARNING **: Error loading theme icon for stock: Unable to load image-loading module: /usr/lib32/gtk-2.0/2.10.0/loaders/svg_loader.so: /usr/lib32/gtk-2.0/2.10.0/loaders/svg_loader.so: cannot open shared object file: No such file or directory

I've attempted to follow the instructions on one of the previous threads that mention this but it didn't resolve it. My main problem though (doubt it's related) is that I can load the game just fine and go to the character selection screen without any problems (even sound works) however 9 out of 10 times when I attempt to enter the world it just segfaults. Usually when I actually make it into the world things are fine (which is why I don't think the previous warning is the issue) though once I entered the worold and was completely alone (no enemies, NPC's or other players). Terminal doesn't give any info besides crash_backtrace_xxxx.log recorded. Here is a copy of my latest crash_backtrace.log
