2. If steam crashed (Segmentation fault on line 700) "steam --reset" is your friend.
2a. If --reset does not help - remove ~/.local/Steam and redownload stuff
3. If game is asking for some library, you can detect it:
./bin/32/kAGE: error while loading shared libraries: libXaw.so.7: cannot open shared object file: No such file or directory
you need to search which package provide that library.
# apt-get install apt-file
# apt-file update
# apt-file search libXaw.so.7
next step is tricky.
Hopes you already add i386 arch to your system. If not:
# dpkg --add-architecture i386
# apt-get update
You need to install _i386_ version of missing library.
# apt-get install libxaw7:i386.
and it will run smoothly.
