Greetings.
I'm not a developer take therefore what I say with a pinch of salt. I
doubt netbook-launcher actually crashes. Gdb says it the program exits
normally and no backtrace is available. Instead please look at attached
strace output where starting from row 2463 you will find the following
output:
